Some suggestions

[mossaiby]

WinBox is already great. Here comes my suggestions after working with it for a few days:

1. Some events can be added to enhance the look and feel of the UI, such as beforeMove or afterMove, so that one can for example decrease the opacity during move. This was pointed out in another issue as well.
2. Snapping to other windows edges can be great. See an example here: https://davidfig.github.io/window-manager
3. One window always remains focused, even if you click outside all windows. I think there should be a workaround for this. If you make two windows and minimize them, then close the focused one, the other one doesn't get focused, which is inconsistent.
4. Some window presets can be great.
5. RTL support can be great, though I could do that using CSS. This could be integrated in WinBox.
6. Support for other shapes for minimized windows could be great; see the picture below. The green button is in fact a minized window (like the one on the right). It is even movable. At least the shape part can be done using CSS, if things are not hard-coded in JS.
   

Thanks!
