The font size change happened from 3.4 to 4.X new theme? Or did my eyes just oversaw a new Change from 4.2 to 4.3?
Yes, PVE 3.x shows 12 rows where 4.x shows only 10.
Doesn't sound like a lot, but when you have to manage a lot of guests, it quickly adds up and you have to scroll a lot more. So I would very much like an option to set font (and list item) size in the new GUI.
