Overall, Flitter 3 has some great improvements. However, one thing in particular is driving me crazy: In order to go to the article on the original site, one now has to bring up a menu, then select the option. Previously, this could be done with a single tap from the main article view.
Unfortunately, most of the RSS feeds I read do not include the full text of the article in the feed, so I'm constantly using the go to page button. Now the number of steps needed to access it have doubled. It may seem like a small thing, but this was the single most-used option on the toolbar for me, and the new placement is becoming irritating very fast.
