With this, the codebase is mostly typed (as much as sumneko's type checking allows), and finally go-to-definition-able.
This refactor changed or touched more than 90% of the codebase, so here's just the most notable changes I can recall:
Menu implementation is now way more robust, and supports:
- live menu updates
- opening submenus allows navigating to parent menus
- items icons and bold & italic styling
- keeping menu open after selecting the item
- peeking submenus
- and a lot of other small tweaks
The menu input data structure changed. It no longer accepts `active_index` and `selected_index`, instead, each item can now have `active` or `selected` property.
And I'm sure there's a lot I'm forgetting to mention, but it's midnight here T.T
