Currently there are 30+ "programming languages", 20+ "scripting languages", 9 "markup languages" and some "Misc" languages.
The first two categories are so big the menu (Document->Set Filetype->) won't fit on screen (at least with a laptop).
Especially the first should be broken up. This is a call for suggestions of how that should be done.
Otherwise I will make a pull request breaking them up in a reasonable but somewhat arbitary way, rough popularity measure and degree of support. :grin:
