menubar
The application "state" VIDE is in, is more or less persistent (if development keeps up).
As of now, VIDE remembers its open windows their size and their positions.
There are a few "main" windows and quite a few "child windows". Once any window is open - the gui makes no difference between main and child.
"My" difference between main- and child- windows is the place where they can be opened. Main Windows can be opened from the Menubar, there from the menu: "Tools":
menubar
All other (child) windows are opened from the "main" windows.
Each window is accessable (uniconify/bring to front), via the window menu
Using CTRL/TAB gives access to a "quick" Window switcher
Windows can be iconified to the desktop
Thru tinylaf, themes are supported
