I recently switched from Windows to Mac M1 running Big Sur and can't find a feature that I had on my Windows Laptop.
On windows, I had AquaSnap installed, which has really nice features. One of those is that when windows were next to each other, I was able to resize the windows simultaneously when they were next to each other. E.g. when I want to make one app bigger and the other side smaller, I just pressed Ctrl while dragging one app to a side and both sides got resized.
I found a video on YouTube where somebody did this on the Mac, but in the video, both apps went into full-screen mode (and obviously shared the space). However, my Mac does not behave like this (i.e. does not go into full-screen mode and also does not resize both apps simultaneously when resizing) and I think this behaviour was part of an earlier software version.
Is there another (simple) possibility to activate this feature?
It is worth mentioning that on my Mac I have BetterSnapTools installed, but did not find such a feature there.

Option 1: Native Split View in Big Sur
Make sure you have at least two windows on your desktop
Start by hovering your mouse over the green maximise button of one of these windows
Click on "Tile Window to Left of Screen"
Then, choose the other window, which should become the right part of your tiled window arrangement, by clicking on that window.
When you adjust the width of the left window, the right window will resize accordingly.

Option 2: Tiling window manager
If you would like more configurations options, or you would like to extend this mechanism to more than two windows on one desktop, using a tiling window manager like yabai would be an option.
For example, if a couple of windows are on one desktop using yabai, resizing one of the windows makes the other windows adjust their sizes accordingly.
Install the homebrew package manager
Install yabai
Adjust the configuration in
~/.yabairc
if needed to customise the tiling behaviour.Have a look at this wiki to learn more about the tiling-configuration options.
