Good shot but it has a long way to go before becoming usable as my twitter client of choice.

Can we have the possibility to choose from system fonts for the tweet list?
Can we have a post tweet box resizeble (and more differed from the list)?
Can we have the timestamp in a font size differed from the tweet text?
I can go on and on. As you can see are all UX/UI problems. The mainframe is there. It lacks a proper UI.

I like it as a barebones twitter client and i hope in some of the above improvements.
Keep the good work.

NatsuLion is lovely. Works fine, pleasant to look at and eats almost zero system resources. And developer is really active with updates and bug fixes.

NatsuLion has become my Twitter client of choice. It's on par with Twitterriffic in features, and doesn't have the annoying HUD interface. Plus, the price is right and no ads.
