Customize this screen is very nifty and I see lots of little improvements too (browse tags, clearer labels, icons replaced with text, better action bar, simpler looking date). I'm not sure drag and drop's obvious enough but it sure is awesome. However, I still dislike the styling, I still wish Save and Preview were with Delete and Post and the bar was duplicated below the entry, it still feels a little cramped, and I don't know how I feel about hiding boxes be default either (it's different from collapsing them).

But this version's tons better than the previous one for me. Thanks for listening to critiques. :)
