Picture in picture mode for Arattai Desktop - feature request

I have been using Arattai of late. And I like it's low bandwidth performance. On both mobile and PC.

But on the Desktop version, the video call window, is trapped inside the app window, and doesn't have flexible resizing.

But most annoying thing is that in full screen mode, it gets into picture-by-picture mode i.e. both the callers are occupying half the screen, Whereas, Whatsapp continues with pictures-by-picture i.e. small window of the other person, in the corner, while one sode can fill the screen.

Arattai Desktop should make these changes - picture-in-picture and resizability.
