I recently upgraded to an ultrawide monitor and have been making ample use of Windows's virtual desktops and FancyZones. I have a thumb button on my mouse set to bring up the Win+Tab menu and jump between setups for work, gaming, projects, etc.
I never really used virtual desktops previously (usually on a laptop where it didn't make a huge difference) but the combination with FancyZones has really been a game changer. I'm sure some linux folks are laughing at this being considered a novelty, but it's a very seamless setup.
