🌟 A Primer on Using a Project Outliner

What Is a Project Outliner?

A project outliner is a powerful tool that lets you organize information in a hierarchical way. Its core functionality is similar to that of a bulleted list you’re probably familiar with after years of using word processors like Microsoft’s Word. But there’s more to outliners than meets the eye.

One of the oldest tools in the outlining flock is Org Mode. Released back in 2003, Org Mode is an advanced extension for the classic Emacs text editor. On top of Emacs’ text editing magic, it adds features like foldable hierarchical lists, to-dos, a calendar, and more.

The only problem? Org Mode isn’t exactly user-friendly. 👇

The good news is an outliner is just a vessel.

Modern outliners offer a holistic, end-to-end approach to project management and cover all productivity bases, from planning through collaboration to task management. Some will even let you transform outlines into interactive mind maps. But more on that in a bit.

With the power of outlining, you can bite into infinitely complex projects and break them into a series of incremental steps or tasks. After all, a problem or idea is just a sum of its parts.

And now, let’s get down to business.

🤹‍♂️ What Can You Use a Project Outliner For?

The overarching purpose of outlining software is to organize information in a hierarchical way. This is usually done with two outlining operations–nesting and folding/unfolding. Both let you highlight the connections between tasks and easily filter out list elements.

“Aren’t outliners reserved for writers?” That’s an excellent question. Writers love using outlining software for taking notes and structuring documents. But a project outliner is a much more versatile tool that’s excellent for anybody who needs a simple but powerful solution to…

  • ✅ Manage all tasks in one simple tool.
  • ✍️ Capture information/take quick notes.
  • 👑 Visualize all kinds of hierarchical systems. 
  • 📝 Plan and structure documents before drafting.
  • 👁 Plan, manage, and debrief projects.
  • 💬 Prepare a meeting agenda/talking points.
  • 🪨 Break complex ideas/problems into chunks.
  • 📍 Connect the dots between ideas.
  • 🔄 Create reusable checklists and templates.

An outliner is the Swiss Army Knife of productivity. It’s perfect for personal and professional projects of varying scope and complexity as well as any enterprise that requires a holistic approach to problem-solving and brainstorming. 

⚙️ How Does a Project Outliner Work?

Every outline starts as a linear index of elements. It can be something as simple as a grocery list or a makeshift meeting agenda. In order to transform those lists into proper outlines, you need to learn a few basic outlining concepts and operations.

Parent/Child Elements

The fundamental mechanic that makes an outline “tick” is the relationship between parent and child elements. For simplicity’s sake, let’s call them tasks and sub-tasks.

A task (parent) is a superordinate element of an outline that occupies the highest level of a hierarchy. A sub-task (child) is a lower-level element that’s “nested” under a task.

An outliner lets you quickly highlight the relationship between tasks and subtasks by indenting or nesting lower-level elements in a hierarchy. But there’s more.

Folding/Unfolding

The division into higher/lower-level elements is a great way to visually identify tasks and sub-tasks and their position in a hierarchy. That brings us to folding/unfolding.

Fold/unfold is one of the most important operations in a project outliner and also something you can’t do with pen & paper. Simply put, it lets you “hide” a specific level of an outline and every child element nested inside that level.

#Tags and Formatting

Project outliners make it super easy to organize information out of the box. But why not take things up a notch with a selection of styling/formatting options and color-coded #tag?

Typical outlining tweaks include different heading and bullet types as well as basic formatting options like bold, italics, underline, and strikethrough. #Tags, on the other hand, add granularity and allow you to easily filter out project contents.

#Tags and formatting options improve content organization and task management without adding unnecessary complexity. It’s as close to distraction-free productivity as it gets.

Keyboard Navigation and Shortcuts

Many outliners are optimized for keyboard use. One cool benefit of keyboard-oriented workflows is the ability to get things on the (virtual) page blazingly fast. 

We build Taskade with keyboard shortcuts in mind so you can build outline levels without taking your hands off the keyboard. You can check tasks, edit outline structure, fold/unfold levels, and apply formatting options using just your keyboard.

You can visit our live demo page to test a few basic key combinations. Start with ⌨️ Tab/Shift+Tab to indent/outdent, ⌨️ Shift + ⬆/⬇ to select multiple elements, and ⌨️ ⌘ + Enter to “check” a task.

Project outliners come with cross-linking capabilities so you can easily connect tasks, notes, documents, and insights to get a high-level overview of every project.

Internal links are also perfect for combining individual entries as well as entire projects into clusters. Connecting the dots help save time when projects get hectic.

👑 Project Outliners Are the Apex of Task Management 

With the productivity space as it is now (read: crowded), you may be wondering: “Do I really need another app to get work done?” And that’s a perfectly valid question.

The problem with modern productivity stacks is that they’re anything but holistic. We got to the point when there’s an app for everything. Heck, we need apps to manage all the apps we, well… supposedly need. That’s a long way from true productivity.

Project outliners, on the other hand, offer a back-to-the-roots approach to productivity based on the familiar concept of a bulleted list. They are…

  • 🌩 Fast, lightweight, and reliable (cloud synchronization)
  • ⌨️ Designed with efficiency in mind (keyboard-oriented)
  • ♾ Like an Infinite canvas for brainstorming and problem-solving
  • 🧠 Geared toward metacognition and critical thinking
  • 🧘‍♂️ The best medium for holistic task management
  • 🤝 Fit for real-time collaboration (more on that down below)

Unlike bloated, future-rich platforms that get in the way, outliners are extremely lean but still pack a powerful productivity punch. Plus, most project outliners are also modular which means you start with a list but can progress to infinitely more complex—and still blazingly fast—constructs.

🤖 The Rise of Collaborative Project Outliners

Wouldn’t it be cool if you could pair the simplicity of an outliner with powerful collaboration features to get work done with your team? The good news is you can!

Taskade is a modern project outliner and task management app that helps teams plan, work, and chat using one unified platform. And, in case you’re wondering, everything syncs in real-time! ⚡️


Team Communication (Chat, Video Conferencing, Calls)

Taskade features three communication channels⁠—video conferencing, chat, and regular VoIP call⁠s— so you and your team can discuss whatever you’re working on. 

Every outline you create is essentially a self-contained team workspace with an integrated chat window. You can send direct messages, start a video meeting, or jump on a team call without shuffling windows or leaving the app.

Planning (Calendar) and Task Management (My Tasks)

In Taskade, every outline is essentially a to-do list, complete with due dates, #tags, and task owners. All your tasks and sub-tasks are also visible in a shared Calendar and My Tasks space.

My Tasks include information like task due date and task owners. The Calendar displays all tasks and projects with due dates and/or date ranges across all Workspaces. This way, you can easily track everything that happens in your team in real-time.
