Just needs to be polished up a bit!

An awesome menu bar icon that let you know of new tweets: necessary.

Scrolling up to refresh would be nice too.

Looks a lot cleaner when you hide the menu bar.
A cool idea would be when you click in the tweet field the bottom drops down a bit revealing some nice grey buttons for stuff like inserting pictures, safari or hopefully Chrome and Firefox pages.

Using this for just a few hours and I already like it a lot really hope you continue development!
