Yesterday Reeder for iPhone was updated with a feature I've long wanted, namely the ability to assign a specific action to the gesture of sliding an article title to the left in the article list view.
I've set mine to "Send to Instapaper," which means that when an article's title has enough information for me to know I want to read the article later, I simply slide the title to the left, and can immediately continue scrolling. The action itself is so fast and fluid, and collapses what was four touches (i.e., Title > Services > Instapaper > Back) into just one.
I know I've said it a million times, but this app is untouchable. Silvio, I love you.
Update: I'm told that this feature has been in Reeder for iPhone for a while, and that this latest update just added Readability support to the mix. (Thanks MacMacken.) How did I miss this the first time around?!
