ifonline,
Hub List is entirely written in JavaScript. It does not use any UI toolkit components from Titanium. Appcelerator Titanium is soley used for packaging into native desktop application formats.
I've spent quite a bit of time getting the UI pixel perfect to Mac OSX UI standards so please give it a shot before knocking it or pre-judging.
Also on the mobile front,
Appcelerator Titanium is not currently in violation of Apple's TOS. There has been a lot of discussion about this recently you can find more info online.
Thanks for the interest in Hub List! I'd love to hear anyone's
feedback and experience using the app next week when the first beta comes out.
