TODO

add posibility to select refresh time
implement cache eviction strategy instead of simply clearing the cache when it's full
log in on app start up
Usability Urgent - save username and password so it doesn't need to be entered 
 add a checkbox to select the option
Fix scroll issues, add pages scroll where necessary (found users for example) 
 
 Add support for selecting individual tweets
	* follow/unfollow button depending on the following status of the user selected
	* retweet button
	* direct message button
	* selected user information (tweets sent, account info)

Add posibility to open links from tweets


optimizations

background updating of tweets, maybe a switch to Twitter stream ?
display unread tweets on buttons, or at least a signal that it has updated
Only start wireless when necessary
retrieve only messages that have not been retrieved before (possible ?)
Additive timeline instead of replacing, up to the last xxx tweets to be decided in settings
API usage caps checks !
