[Geany-devel] Request: multithreaded tag generation?

Good one, does navigation, now all we need to add is completion :)

And after all, this is how ctags has worked in editors since emacs was
a teco macro and vim was a vi in short pants.

Yeah, sadly that makes my suggestion of saving the tags unlikely to
save much time, though I havn't tested it, anecdotally loading large
saved tags files is still slow.

Lets encourage and help Colomban with his experiments of replacing
tagmangler, and add ctags loading.
