On a default Win10 system, pressing e.g. Win+Left pushes the current window to the left edge of the screen setting its width to half of the screen. This is an awesome feature and I love it.
However, I can imagine additional greatness to said feature. The screens are getting larger, so half-screen-size is rather large. I'd like to be able to put a window in side-by-side mode but setting its side to e.g. one third of the width.
That way, I'd be able to quickly set up two long but narrow frames on the vertical edges and in the middle, keep the working area free or, perhaps, divide it into upper and lower halves.
The closes to it I've found is Win+Left+Up, which lets me set up a 2x2 array. It's okay but not perfect. Googling the issue gave me nothing except a noob blogs going bananas over the feature as it's described above. Nothing about going beyond it to more complex window arrangements.
Primarily I'm looking for a built-in way but since I'm rather certain that there's none, I'm also open for a suggestion on a utility that might achieve corresponding result.
