If you have multiple tabs open in a floating window in L4, it would be helpful if the software warned the user before trying to close the window if it has multiple tabs open (similar to the way most browsers warn the user before closing if multiple tabs are open). It is easy to hit the "close the entire window" 'X' by mistake when the user really meant the smaller 'x' to close just one tab in the window.
Just a thought.
Logos 4 is really great, BTW!
