6. It's not clear how to create a new document.
7. How do I refresh the tree? I cant!... oh wait, if i click "do something else" then I get the option. Very confusing
8. The slide out panel needs to be more noticable. I didnt even notice that it appeared. It should slide out, be a different color, and have a hover state.
9. It's not obvious that I MUST enter a document name.
10. The document name is at the top left. So why have the name field under the properties tab?
11. I really think loosing right-click is going to cause usability problems. People are very used to doing right-click in the desktop scenario. If it looks like a folder tree, people will try to right-click it and expect some sort options.
