Projects

Cards live in a nested project tree - a folder structure where a project can hold sub-projects as deep as you like. Drag cards or whole projects to move them, and filter the list to a project to focus on one piece of work. Two quick views sit in the sidebar whenever they apply - Unsorted (cards in no project) and Untagged (cards with no tags) - and you can unlink cards from a project to remove them from it without deleting them.

Unlink from project	Removes cards from a project without deleting them - the selected cards, or all of the active project's cards (with a confirm).
Also delete all cards in this project	In the delete-project confirm: ticked, the project's cards are deleted with it; unticked, only the project is removed and its cards remain, showing under Unsorted.
