Awesome update!
A few design ideas:
-Change the button order to [+][-][Save]. Even moving [Save] to the right side of the modal as well, to give it some separation. This would make the buttons more purposeful and make it look less crowded.
-Change the FA tooltips to reflect the site name instead of the FA icon name. Between .fa-youtube-play and YouTube, it's easy to see which is the friendlier name.
-Find some way to make the icon contrast clear against the different colored profile hero images. Against darker images, some of the black icons disappear almost entirely. Maybe a background, border or glow, if you're not willing to use a color overlay on the icon itself. EDIT: Looks like this is just a bug on Firefox, on Chrome the option for greyscale images appears after re-clicking the icon selector.
