Tremulous 1.2 is currently under development, most of which, as I understand it, concerns gameplay changes and balance tweaks.
Other than these sorts of things, which have been discussed and are being play-tested elsewhere, what would you like to see added to 1.2 which already exists as a community add-on? Not some cool idea that you've heard of, but some feature which you can already currently add to Tremulous that you would like to see bundled with the next release.
As for me:
1) an "official" Mac client (w/ fixed sort-by-ping)
2) backport included
3) Options pane on Play page
4) brightness as a menu option
That is, just a basic and lightly patched client, all-in-one download, for each separate OS, somewhere on the main site. (Oh, the vote system looks pretty cool, also.) As I've said elsewhere, this might even be a good idea as a 1.1.9 release, to re-energize the community prior to 1.2.
