"""Tagit standalone user interfaces.

Tagit contains several submodules:
* apps: Launchable standalone applications.
* windows: Compositions of various UI functionality.
* widgets: Individual UI components and core functions.
* dialogues: Pop-up dialogues.
* actions: Single actions that can be performed on widgets.
* tiles: Display a digestible amount of information.

Additional core functionality is provided by some generic
modules (utils, parsing, config, etc.).
