Command palette as native feature

[FliegendeWurst]

I recently found this neat widget: https://github.com/justyns/trilium-scripts/blob/master/command-palette/palette-testing-widget.js

It implements a "command palette", a feature found in many other programs already (VS Code for example).
The command palette is a dialog where the user can search for actions, like "create new child note" / "activate zen mode" / ...
If an action has a keyboard shortcut, it will be displayed as well.
It is mostly useful for rarely used actions where you don't know the keyboard shortcut (or actions without a shortcut).

If it were implemented in Trilium natively, it would be much easier for other scripts to add custom commands.
And since we already have several "search -> select -> do something" dialogs it shouldn't be too hard to integrate a basic version.
