Huh, thanks for noticing. I have a retina display but on Linux Chrome and Firefox both ignore any kind of global font size settings for their tabs, so the icons are tiny and look crisp, didn't realise. That kind of thing bugs me too. The rest of the layout itself should be retina-friendly, though, as I developed it like that.
