It's lite on content at the moment, (and also may not work everywhere for the next couple of days thanks to DNS) but hopefully this will let me address number 7 via the forums and number 8 via the gallery.
6 is done - actually using the default browser for the view blog function. I think I'm doing pretty well for number 5, and number 4 should probably be implemented in a couple of more places. Number 1 is a big duh and should have been done since day one. 2 sounds like an interesting problem and will require a little more thought (although initially I'm thinking something like the auto-saved draft feature in gmail)
