Low-priority but very much a "nice-to-have" IMHO and a "restore old VBB functionality".
We had, as do most/all VBB forums, a dropdown box at the bottom of each forum index page, and each thread page too IIRC, to jump directly to any forum.
This was very convenient, especially as its location was at the bottom of the thread index or thread content page. So if you were done with that topic, you could immediately hop to somewhere else on the forums.
Yes, I know we have breadcrumbs at the top of the page to back up a level or more, but this direct-jump dropdown was much more convenient.
Please consider adding it. Thanks!
