I don't know if i could finally manage this. But here is one idea.
Has this forum the possibility to vote for threads or mark a thread on a scale from one to five stars? Or is it possible to add in the subforum "Nice to Have" a counter to the threads? In this case users could post features they like to have in this forum. Other users could increase the counter to show that they like to have this feature, too.
The developers could see how many followers a feature request have. If it is not possible to implement a feature the developers could answer to the thread and edit the thread title.
Don't know if this forum could do thinks like that. Maybe a forum administrator could check that.
