There's others, but this is what I've pulled out of the threads so far.
Wishlist:
* Select on Consider
- Not sure if this is even possible
* Stats, AA, EXP, ...
* Searching mob list by entering a string in a dialog
* Hotkey for highlighting the current target
* Optional breadcrumbs behind mobs
Known Bugs:
* X, Y, Z, Dist in the listbox don't update.
- Performance reasons.
* Port changing still doesn't work in 1.9 server
- Fixed and waiting for release
* Big red X instead of map.
* Win98 & ME issue still seem to exist.
* Maybe a couple of network issues causing the client & server to get out of sync.
* Horse level being used instead of player level
- I've got no idea what's going on here and can't test as I have no horse at the moment.
* Jumpy map in general.
