1. You can't pick and choose your monitor like this on laptops.

2. I like my "window/s of interest" (the current "task") to be front and centre; I would like my window management when task switching both to do this for me and to set the previous current task aside for me. It seems to me this would require some kind of undiscovered paradigm that isn't tiling or stacking. Ultrawide is just forcing me to direct my attention to a specific off-centre region for extended periods. This feels like holding breath, except psychological - I can only take it so long, then my eyes, by themselves, are going to look at other areas, whether I like it or not. Which is also one reason why tiling is an absolute non-starter for me.

32:9 is amazing, the Snap Windows feature on Windows gives me exactly what I want for tiling options. But, whew, physical real estate is killer. I've got a huge desk (Biomorph Pro) and the 49" double-wide display makes it feel cramped.
