This isn't really a suggestion for a module.  This is more of a suggestion for the layout of your forums.  I would suggest having a "Feature Requests & Enhancements" sub forum in each module forum.  I would also recommend sub forums for "Community Support and Questions" for each modules forum. 

I use this forum on one of my sites and it has been trouble free so far.  I haven't had time to play with the formating of it much but from what I read it is very customizable....Good choice on the forum software.

Good idea, I subscribe to this idea !

Otherwise, could you rename each subject in the main forum to include the name of the module ???

 Or even a better idea... Why not using Ventrian Feedback Center ??? Each user can ask an enhancement, and then, everybody can vote, you will better know which one is important, which one is not, etc...
Should be better for the developper and user... Otherwise, you will soon be lost with request, and managing priorities... This is a suggestion...
