Switched info to `i` and found a pretty nice external link icon imo. @tophf As for pixelation on the info icons, you mentioned maybe a lighter color would help. For all icons besides external links, I made them lighter with darker hovers. Besides a really high zoom, I never saw any issue to begin with, but let me know if they're alright. I also changed them to use their exact original dimensions, so maybe that helps.
Max height is 600px for the popup, regardless of resolution (so says Google), so we can set the styles section to a max height in px and let the overflow scroll inside the div, instead of scrolling the whole popup. This way the other actions are always present at the bottom of the popup without needing to scroll to use them. I left a little breathing room for the rare instance when domain name in "write style for" is long enough to cause a line break, so there should never really be any overflow for the popup itself.

The icons I used are from right here on Github. They're SVG, so there should't be reliability issues. Wanted to see how they'd look, and I really kinda like it. Thoughts?
