If the author of ProQuake were ever to do more development to the engine, a list of reasonable improvements would be:
1) A time command as I can't exit GL ProQuake, which I run in full-screen mode, and return without the graphics being messed up. Would be nice to be able to check the localtime by typing "TIME" or something.
2) Custom map download a la QuakeWorld
3) An "*" or something on SHOWSCORES next to players names using ProQuake.
3a --> Maybe a mixed-cheatfree mode with players using that mode with an indicator next to their name.
4) Support for the numeric keypad keys.
5) Whatever fix of the style Yugo2Heck did to the server side code so in server mode the "Cannot Connect to Server" problem is bypassed like implemented at quake.ihoc.net and xoc.ihoc.net
6) Somehow make the client so it get "news updates" or informational bulletins from
http://www.planetquake.com/proquake or maybe RuneQuake.com, since this site is one of the longest lived ones. I'm just talking about maybe some text popping up retrieved from a text file sitting on a specific location on a web site.
7) Maybe an "installer" on installation that offers to get additional files (maps, popular mod downloads.)
8 ) The ability to "lock" your config.cfg (set as READ-ONLY) so it can't be overwritten.
[Most players use quake.exe or winquake.exe and that client has really issues to connecting to servers and whatever change was implemented at quake.ihoc.net somehow bypasses this problem merely by a change on the server side. More information is in another thread on this topic.]
I know the last release was in 2002. Who knows if there will ever be another release, but you never know.
