I see a lot of nice cosmetic upgrades, and I have no doubt there are many "behind the scenes" fixes.
Right now, the most important thing that is broken, for me, is the "preview pocket query in Google Maps". There is no longer an icon for that in my PQ list. The "preview" icon now takes me to a new page which looks like it will be cool when it works. Sadly, it seems stuck on Green Lake Park. The "tab" links are also dead ends.
I'm sure everyone is working very hard to swat the bugs, and get things rolling smoothy, so this is not a complain-o-gram. Just a note.
