Feature request: Button to "pin" a window (always on top)

[redsolver]

Basically have a little pin icon which when pressed causes the window to always be on top of all other windows. This is useful for pop-out video players or audio controls for example.

You could just use a browser with PiP (Picture in Picture)

You could easily accomplish this with CSS.

.winbox.pinned {
  z-index: 9999 !important;
}

new WinBox("Pinned Window", { class: ['pinned'] })

Adding custom controls to the window toolbar is now supported. You can combine this with the workaround above.
