I'm not sure of the best way to ask this question because I don't know the correct terminology for what I'm asking about.
When I drag a window to the edge of my screen it automatically resizes to occupy half the width of the monitor. Same with the function key + left/right arrow. They both make the window resize to a 50/50 split for each side.
Now, I have a 26" monitor and I find the best setup when coding is a text editor taking up 75% of the width with a terminal taking up the other 25%.
Is it possible to somehow make it so when I drag against the right side, the window resizes to the right 25% of the monitor, and against the left side the window resizes to 75%?
Surely the 50/50 ratio must be stored somewhere? Can I just edit that to be 25/75? Or an arbitrary ratio?
