The maintained window is just kind of a pain to modify. It's like 30 pages over and over, rather than some form of template, so it's very tedious to have multiple version to "maintain" (hah). The easiest way is to just modify the layout of the first icon and copy and paste it in a text file and then edit the ones after it, but still.... quite tedious
As for the window scrolling, I'll have to look into that. I thought it was by default, but *shrug*
I saw on test server that certain beneficial spell procs weren't gonna show up in the maintained window anymore, so I'm hoping that some clutter could be reduced soon.
