sure TwinTails,
I found some forum articles in here on making your own custom borders and enabling dragging the mouse on it, below is the closest example, i can't find the others but you get the idea.

I think the new node-webkit exported for C2 might have a bug, because i also tried editing a file within the exported targeted OS and it didn't work, i can provide all my research on here if you like.
to test this bug on your machine, go to the folder where you are running the game, and look for a file that has the following extension .nw, open it using 7zip, winzip, winrar and look for package.json file and edit the "window" : section to apply what you are interested in testing, for me was the frame save it and run the game, see what you get.
