thanks for the feedback! we're slowly rolling out a bunch of css changes so glad you like it. the colors are gone mainly to bring more focus to the editor. we are trying to use color as sparingly as possible because we really need it to be focused on multiplayer, syntax highlighting, etc :)
Hmm, they are rounded for me. I think the update is pretty cool especially the new teams feature. And your website is cool too.
And I like the fact that the colors are gone, it seems more serious.
