Using Alt-Tab to switch between windows using the Monocle engine

Is your feature request related to a problem? Please describe.
I did search the issues, but could not find any. I am using two shortcuts to switch between Binary Tree and Monocle engines. But, when I am using the Monocle engine, I need to use a different set of shortcuts to switch between the windows. But, that makes it uncomfortable, when I need to switch between two recently opened windows, then I need to cycle back between all the windows I already opened. Even trying to select a different window from the task-manager does not work. It just previews the window, but goes back to the original one.

Describe the solution you'd like
Use the already implemented Kwin switcher for all the engines. For tiling engines, it does not make a different. But, for a Monocle engine I think it would be a necessity.

Describe alternatives you've considered
I do not see an option to switch between the recently opened windows in Polonium.
