What stands out in fancy zones is that these areas do not have to tile each other and may overlap. Positioning windows in there is also very UX. I couldn’t find anything close enough in linux world (well, one may always program i3 or awesome, but it’s beyond my scope of interest).
I don’t get why MS doesn’t just build it into windows, since it’s their own, free tool.
Second FanzyZones. I've remapped the keys I could to mimic i3, and the only thing keeping it from "perfect" is keyboard shortcuts to control splitting/moving/resizing. You can toggle between pre-configured fixed zones using the keyboard, which is mostly good enough.
PowerToys also has a ton of other useful tools like a color picker, bulk file rename, and keyboard remapping (useful when using Synergy between Windows/MacOS). Highly recommend.
One thing that cracks me up is how many of my users request multiple monitor setups, but look at the keyboard while they type.
