(Feature request) UX: Code blocks: sort mime type by most used

[maphew]

Describe feature

It would be nice to have the most often used mime types in Code blocks sort to the top of the list, or have find-as-type. For example I rarely but not never use C or C#, which are close to the top, but often use Shell. I don't want to remove C from the avialable types, but navigating past them for 95% of my uses is unwanted friction.

(Alternatively, perhaps an explanation of how autodetect works might reveal some tricks that would be less key+mouse movements than using the toolbar dropdown to begin with.)
