I actually like the new version and its look.
But I also feel the pain of Power users that used Evernote to the max and now their workflow is damaged / gone / changed.
The good thing is that the updated are coming fast.
Also, Evernote team should be more open about roadmap. Color tagging was used by me a little bit, but it seems that some folks used it in a big way.
I had similar experience few years ago when workplace Outlook database was migrated and i lost all my tags.
