I want to switch from Windows to Linux for my office PC.
I will be using multiple Windows VM because in the office we use multiple software that runs only on Windows (maybe we’ll switch to something else, but right now I need the VMs) and because i like to snapshots and go back in time when I test new software.
I thought about Ubuntu because it seems to be the most user friendly.
I always work with a tons of opened windows (mainly Firefox) and I like to have a place for each of them, Right now on Windows I use DisplayFusion that creates multiple virtual screens (7, 4 or the 32" horizontal monitor and 3 on the 28" vertical one, both 4K), I’ve attached the configuration.
So, the question: is there a software that works kinda like DisplayFusion? (virtual screen each with it’s own taskbar, maximize in each of them, remember the position of each window, …).

P.s. Can I pass only some USB port to a Windows VM using KVM?
Pp.s. Is it possible to use Premiere on a Windows VM? Would it run smooth?
