[HELP] How to group three windows in details?

Additionally it would be nice if it was possible to embed them to right panel like addonskins does but on a 3 window layout, I've explored dozens of addons like S&L, Windtools, Nuts&Bolts etc. and noone has that functionality.

I have 0 idea about coding so I cant really write a details script to place them.
