[Feature request] Always-on-top for app windows

[Fan-iX]

I think pinning the window to the top would be a handy feature, especially for those text editor windows.

(The placement of the trigger control may need some discretion, though.)

[o-sdn-o]

Perhaps we need to make a context menu (Mouse-Menu by right click) for the window and for the taskbar elements and place this trigger there. This will allow users to enable “Always-On-Top” in the same way both in the window and using the taskbar. It will also be possible to bind a hotkey to this switch when keyboard support is implemented.
