Inversion to "List subforum in parent-forum's legend"

I know that this is a little bit feature request but it's so principal that it could be marked like bug.

All of us know feature "List subforum in parent-forum's legend".

But feature "(List/don't list) subforums in legend of this forum" is needed too! I need so much for my forum

I don't understand why it isn't able yet. I think that creating of some MOD is useless. This elementar feature should be in official release.

Please, support me (or tell me where is place for feature requests?)
Thank you very much.
