label.dll can display multiple lines as of v1.5

I don't think it auto-wraps though, you have to manually insert linefeeds.

I think there's a module that basically emulates notepad in a minimalist way, maybe it's LSNotes, I dunno I've never used it, just seen it in some themes. I imagine it would let you create noteboxes with pre-specified text.. If not it couldn't be too hard to mod the source to allow that.. Worth checkin out i guess if you're lookin for that functionality..
