I use https://rectangleapp.com/ on Mac and it's great. I mostly use shortcuts Left Half and Right Half, and also Maximize (Not the fullscreen mode thank God)
I appreciate that! When I switched to MacOS, I demoed both Rectangle and Magnet and found that, despite being paid software, Magnet offered a much more intuitive experience.
I'm happy to pay for software anyway, but after spending $4000 on a computer I expected such basic desktop manager features, which have been common since the 90s, to come with the package. This is not something extensions are supposed to do. This kind of crap is why I ditched GNOME.
