In Nestr everything is a Nest. From the biggest circle to the smallest task. A nest can be anything depending on the labels you give it.
In its most basic form a nest looks like a simple task. You give it a name, a description, assign it to someone and it can have a due date. On top of that, it can have labels, sub-nests and you can comment on it. So in it's simplest form it looks like a todo or a task.
Any nest can have children. This means you can have a nest within a nest, within a nest... to infinite depth. If you type a label like #project (part of the system labels) or #your_label when you create a nest and we'll ask you if you want to create a new personal or workspace label.

Nestr has powerful search and filtering capabilities. You can find nests that have a certain person assigned by typing @name of person.

Or by typing #name of label to search for a nest with a certain label.

This is a fundamental concept in Nestr and it is used throughout the app. Combined with the nesting capability described above it makes for a very powerful system.
