The new version took some getting used to, but now that I've familiarized myself with the new action bar, options and the keyboard shortcuts, I like it.

Edit to add: If you have any issues with the three-dot menu in the action bar not working, you might have to disable a conflicting extension. That happened to me – I'd apparently installed another extension for managing YouTube playlists at some point, and while it was enabled, clicking the three-dot menu didn't do anything for me, but disabling the other extension seemed to fix the issue. I didn't think to mention this until I saw a different review mentioning the three-dot menu not working.
