Yeah, I'm not a fan of this. If the expanded was the new 'Normal' i.e. 2 tabs shown instead of 1, I'd have been ok with it, but expanded only being 2 tabs now is rather awkward. I'm sure I can live with it, but I do wonder why they decided to dedicate dev-time to this when nobody (judging from this forum) had any issue with things the way they were.

If it ain't broke, don't fix it!
