Two simple things:
1) option to delete comments from source code when Publishing: we don´t have to make a Ctrl-i Warrior any wiser
2) set x,y coords of a Box. I have used collapse/expand and Lightboxes for remarks (help, messages, etc), but they just do not cut it. If I could only set a hidden/collapsed box at the bottom of a page and show/expand it with coords (even "Center" would work), then that would be a simple, but valuable addition.
