Interesting rethink of the superfluous tag-navigation options. I do find it to be a vast improvement. :) (Personally, it's still a feature I have no use for, but the one little button is certainly a million times better than those hated arrows.)

Just so you know, people who were using custom CSS to get rid of the arrows may now find their tags missing on individual entry views. I found this happening, and when I removed that bit of CSS, the tags reappeared.
