1)
Get rid of the 'no icon' option when doing a post (I actually only want one single icon to be available and a consistent, clean look everywhere)
UBB.Classic had just this, and is a feature I miss.
4)
Have the last poster for each topic listed on the Active Topics table.
I too would like "Active Topics" more updated to "Active Posts" so one can see the latest post time/user vs the original post time/author
