Sorry for the nitpicking, but I think I should clarify.
"Go To Anything", "Command Palette" and "Go To Definition" are three different commands, and they all use the "Quick panel" api, basically part of the interface.
This issue https://github.com/SublimeText/Issues/issues/21
is basically about the quick panel api, and not specific to any of the Go To's. If this is implemented, all commands and every plugin that uses the quick panel would benefit from it.
This issue https://github.com/SublimeText/Issues/issues/14
is about the ordering of files specifically with Go To Definition. Changing the order would maybe result in some Api changes for the quick panel, but it's basically a Go To Definition, and maybe Go To Anything issue.
What I described here viewtopic.php?f=2&t=12379
is a combination of both Go To Def and quick panel, but e.g. it doesn't happen with Go To Anything.
So I suggest categories for all three commands, and additionally Quick Panel. I would gladly sort through these if you would add me to the github organization.
