After working some time with scripting this stands out as a mayor annoyance. Usually I have a big playfield on the desktop and then I start to bring up all sorts of scripts and browsers etc. After a few minutes the desktop is cramped a I have to put a script over the playfield. When I do that the script editor gets D&D on the playfield and usually gets cropped of so it's impossible to read/edit. Script editors could follow the same rules as system windows and have embedding turned off by default.
