Recently I've added some new features to the workflow:
App icons for all apps and their shortcuts.
Search among all shortcuts without selecting an app first (use cheatsheetg keyword for that).
Hide or show only specific apps in the search results. To customize that type cheatsheet keyword, select Customize your cheatsheet, then list needed apps in settings.json (sorry for not implementing a GUI for that). Check also README.md for the settings format.
