Did not think about how higher resolutions would change peoples opinion. I'm using 1920x1080.

68.42% 1920 x 1080
9.27% 2560 x 1440
7.04% 1366 x 768
1.99% 3840 x 2160
1.02% 3440 x 1440
Not suggesting that this means the default has to decrease. Maybe 46 is a good default because it remains usable at higher resolutions? 🤷♂️ While I hate the default for my resolution, its trivial to change it so no big deal.
