I hope MP GUI will get fixed and completed for 0.8.2. :/
I don't think anyone is actively working on it... patches for missionpack does not have to follow patches for baseoa.
The menu definitions for missionpack (like the bot files) was not released with the rest of the source code. fromhell has written them from scratch. They are supposed to have really high priority. Missionpack will make it easier to modify the menus ones complete.
