I liked the previous theme much more, the new "grid" looks unpleasant.

I tried making a custom userstyle for my browser, but the same names are used on many elements and I haven't yet figured out how to only apply a custom style to those under a specific div.

 

Regardless of appearance, the actual functionality has been degraded. Can't load .png files now (at least I can't, gotta change 'em to .jpg), font styles are gone, but I guess that could fall under Appearance..... which is way too muted and bland now.
