[FEAT]: Allow changing of window position in stack

[xidsyed]

Is your feature request related to a problem? Please describe.
When I have several windows stacked, its a bit like the tab feature in chrome, I often want to reorder tabs, depending on which ones are more in use or related. Sometimees im stuck cycling through all the windows to get to the one i want, and can't simply drag and drop the the tabs right next to each other.

Describe the solution you'd like
Allow either (prefererably both)

1. drag tabs to reposition
2. shift active tabs with hotkey (alt + shift + [ ) (alt + shift + ] )
