I want to control many windows without tab thing, just use keys on Numpad to change position and size of controlled area by "+" and "-". For example, there are 4 windows 2 with Virtualbox, and two with a browser, when I'll press "-" I want to see a small area, only Virtual box, and when I press num 6, the area should move and show part of next window. For "+" it's should increase the size of controlled area and show more and more windows.
There is a commercial solution which I found here https://superuser.com/a/173549/761111. Free version from sites google gimespace (it redirects you to another site without free link available) but can move only horizontally and has ads & without key features I mentioned, also top answer contain suspectable software with 7 viruses(can't comment cause have < 50 reputations points) check out here.
