Review my site, nice-entity.com
ugh: I would change the hover color. This will not really be a problem for many users, but with the default OS X selection color – combined with your hover color – entity selections are very hard to see. Since many will want to copy the entities from your site this could be problematic. You could change the hover color to grey or something like that. (This is less a problem with your site and more one with OS X behavior: selection colors shouldn’t be hard to see, no matter the background.)One more thing: It really breaks my heart that this site – of all sites – uses wrong quotation marks. It’s “Find your character!”, not "Find your character!" (Whether or not it is appropriate to use quotation marks for claims like this is certainly also debatable.)
