I like the concept behind this app, and would definitely switch to it from mailplane if a few things were ironed out.

Here is my feedback thus far.

- I think this is a very nice editing of gmails features, I prefer it to the wrapping of gmail's interface that mailplane does

- The interface feels very "Tweetie"-ish, which I think is a good thing

- The tooltips feel really out of place and are obtrusive and unexpected

- I need inline spellcheck for composing messages

- I don't mind the menuling, but either it is showing something other than unread messages or calculating them wrong, also I would like some options off the menuling like compose, or mailplanes fancy do not disturb feature
