A help and or info area that shows your YouTube channel, Moddb page, Forum, ect.
A hide and or minimize button for the Properties and Toolkit Window. When hitting the hide or minimize button causes the model screen to re-size to the new layout.
Basically when moving those windows around causes Windows Solitaire effect. Cool but in the way.
Under the Windows drop down [That you don't have yet], be able to have a multiple or single window selection. Similar to GIMP's
Have this empty spot for quick access to options:http://prntscr.com/7ia3yt
