Yeah you can adjust both of those (row padding and font size) in Preferences>Layout(1)...under "general".
For the "wider gap/separation", have you tried setting the row padding to expanded?
Concerning the size, you can try increasing the default font size...still under general.
Could be wrong but I don't think skins have any control over those two things.
I already spend hours on end on social media. Might as well spare a few of those to a greater purpose here.
