And if you want a single window blown up or made small, you can do it with /window_scale WindowName scale
Window scale will increase/decrease the size between 64% and 199% (expressed in decimal, 0.64 to 1.99)
I use it for league windows to make them more readable.
/window_scale League 1.75 (I'm playing at, essentially, 6K resolution. So stuff that's perfectly viewable for me, at 1080p and .65, is nigh unreadable.)
Note: If the window you're trying to resize is docked, it'll stay at the scale of the parent window. So either rescale the parent window, or undock the specific window.
