Great tool which solves several practical problems. Especially I like the ability to edit documents offline.

After looking at it briefly I came up with these points:

- I'd like to have an easy integration of multiple accounts, like a 'combined inbox', so that I can use quip for private and professional purposes at the same time

- For the desktop I'd like to have an app instead of editing text in the browser.

EDIT:

- In order to make a really great product, add LaTeX support, esp. for maths
