[FEATURE] Context Menu speed improvements. Show in batches

[firefox97]

Problem Statement

I have a few slow items on my context menu like TortoiseSVN etc. I would like some way for some check that anything that is available in the first 200ms or something gets shown, and as slower items become available they show up..
Things like properties and rename should open instantly...

Proposed Solution

I know this is a big one, and there are lots of ideas, and many efforts have been already tried...
Perhaps another option would be pre-caching some context menu sets for a given set of extensions or something? Could load at startup once in idle after loading everything else... And some model for rechecking, perhaps when you click on a file, the cached menu is shown, and it start gathering the current menu items, and if they differ then it updates once the new load is complete, but the user was able to interact with the cached version while loading...

Alternatives Considered

No response

That is not possible AFAIK - OC can ask Windows to provide menu items for selection, and then Windows fires COM servers for all the extensions registered for selected file types, and this only returns the list once all are there, so one slow extension can hold up the entire list.

There are plans to add common items that OC can handle (like new, copy, cut, paste, properties, color tags...) that could be shown instantly and then only query Windows for the rest... the question is how will those be shown without resizing context menu and pulling the item under cursor (and maybe cause wrong item being clicked), are they mixed (like copy being then lower as in standard menu), is the menu shown with some arbitrary size and 2/3s empty (ugly, confusing)... or hidden behind "more items" like in Explorer on Win11 (everyone hates it)

One idea, show the internal functions, as a full menu, and then without moving the menu, add the loaded ones either to the top or bottom depending on room on the screen as another section. So probably looks like 2 boxes stacked.
