Editor: re-click window-opening button closes modal window #208

[Forestidia86]

The issue #208 'Editor: re-click window-opening button closes modal window' is I think an important quality of life feature wish. I think I'm quite used to the mechanism that reclicking closes the opened window in games or that one can click on another button to go to another window.

Thanks for the prod. It's hard to make, but something should really happen.

Unclickable buttons (non-greyed-out) should either become clickable, or I'll have to hide them.
