Since the last update, I cannot apply themes directly or preview them; I need to actually download each theme to use it. I cannot seem to add themes to favourites anymore (or maybe the option is carefully hidden somewhere, left as an exercise for the user).
I hate some User Experience people with a passion.
Edit: Still no way to add favorites, and now the Favorites tab insists I must be logged in to view them. I am logged in. This is a bug. What took literally two clicks before the "improvement", now takes loading at least two pages (Home & Favorites), it's less intuitive and much more of a hassle, in addition to the lost functionality (adding favs).
