FancyZones looks like a godsend for those with ultrawide monitors. Not being able to effectively divide up the space was always a drawback compared with just having two normal sized monitors, this could solve that issue.
I agree. I do have an ultrawide monitor and a secondary monitor and it seems that FancyZones doesn't (yet?) have support for multiple monitors. It looks nice and is useful but I'll be sticking to GridMove for window management for the time being.
