I got the idea from Enhanced Who (http://www.simplemachines.org/community/index.php?topic=22823.0) but all my personal work didn't have much effect..
What i would like is to make this part of the forum Show unread posts since last visit a bit more customisable...
For example to make it possible for users to view new posts forum by forum in colapsable blocks (like categories in index), so, if there is for example one forum with tons of new threads users can disable it from that view, and not to fully remove it (like it is done in ignore forum mod)..
Maybe it is to big job, but surely it would be nice to add some categorisation to unread topics, and if anyone has some idea how this could be easily done or have some code prepared for that, please share.. if i find some solution myself i will post it
