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.
