Maddening on iPad
Missing features from desktop version, no integration with Safari or Mail (you literally cannot go from a link to a doc to this app viewing/editing that doc). When viewing a doc in Safari, you get a constant nag to install this app, even though its installed. Google doesnt use the native detection like everyone else.
Doesnt support iPad multi-tasking, so if you bring up a quick notification from Messages, or pop-over another app, it takes you out of editing mode. When going back into editing mode, it loses where your cursor was.
Pros:
Thankfully, many of the keyboard shortcuts from the web version are the same, and the over UI is less cluttered than the web one.
The document search for this inexplicably works and works fast—the desktop one is slow as hell and flaky.
Overall, its better than nothing, and its easier to use this than to battle the web version into showing you the "non mobile" version, but it could be a lot better.
