Exploration: Supporting command types and filtered searching

[richtabor]

It may be interesting to explore a method of registering a command type, and supporting a method to filter a via that type—perhaps based on an input prefix.

In this exploration below, if you type "?" into the input, you would see all available documentation type commands. Typing a search query afterwards would the filter the results by the input value and the documentation type. This would allow for helpful documentation links within the WordPress experience, while not overwhelming the existing editor interface.

Plugins should also be able to register commands within a specific type (just like how pattern categories work). In the example I have a link that could be registered via the Gutenberg plugin (fetching the version number perhaps), which links to the latest news on Gutenberg. Third-party plugins could add help documentation; hosts even.

Could also be interesting to leverage the prefixes that the editor already uses, like @ to search for users—having each displayed in the palette to navigate to their WP profile. Or [[ to search for posts only.

Perhaps : to search through the outline (headings within post title). Kind of like navigating to a specific line within VS Code.

What other use cases would you see helpful for command types?

The more I play with the Command Palette, the more I like the idea of adding command types. However, more than remembering symbol-based commands, what about supporting natural language keywords/actions like go to, edit, etc? The downside could be their internationalization, but they can coexist with the symbol-based ones.
