KompoZer functionality

OK, I am totally new to NVU or KompoZer, but I like the idea of "on the move" web editing. Currently, I use sitespinner for my websites which serves me really well.

Does KompoZer have similar editing capabilities when it comes to things like using frames and defining mouse on and mouse off attributes? I also will create a text box on a picture I insert, in the end it gets turned into a picture, but I can't seem to figure out how to do it in KompoZer.

All help appreciated!
