FancyZones is a must-have if you use an ultrawide monitor! I set mine up with two zones, where one takes up about 1/3 of the screen and the other takes up about 2/3.
Are you me? Exact same! The problem with dual monitors is either you're sat in front of the gap, or you need to pivot. This way you get a 'normal' monitor and a portrait section to the side, much better.
One 32" 3840x2160 landscape and two 25" 2560x1440 portrait monitors is perfect for me.
