so I have a common situation where I want to show two windows, possibly from 2 different programs at once and need to constantly readjust the y-scale between the 2. currently in windows 7+ there is the window+arrowleft/arrowright shortcut which puts two windows in a even split duel display. but if you adjust the center line - in only selects one window to resize. I want a center line that readjusts both window in relation to each other in once action. similar to how sublime text editor has panels. is there a program that adds that functionality?
