See video in URL for details. Suggestion would be when widgets are "popped out" of the layout (the button to the left of the "close" button in the title bar is clicked), that it not affect the rest of the Kdenlive layout. This would have various benefits to the user and allow for a more customizable use of the program. Reproducible: Always Tested on Kdenlive 15.11.90+48 from vpinon's Wily PPA. Using Ubuntu GNOME 15.10 x64 w/ GNOME 3.16.
