In Nestr everything is an item. From the biggest circle to the smallest task. An item can be anything depending on the labels you give it.
In its most basic form an item 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-items and you can comment on it. So in it's simplest form it looks like a todo or a task.
Any item can have children. This means you can have an item within an item, within an item... to infinite depth. If you type a label like #project (part of the system labels) or #your_label when you create an item 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 items that have a certain person assigned by typing @name of person.

Or by typing #name of label to search for an item 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.
