Thanks, but isn't that only for caching the tiny images within the Reader blurbs. What I'm looking for is caching of the full web page, viewable offline. Byline has this, and so far I don't see that Reeder does.
That said, Reeder is very fast at updating the simple feeds. Many sites only include a paragraph or so, and I really like having the full page available if I need it. It takes way longer to sync, but it is a must-have feature for me.
I think the reason Reeder 2.0 is just so fast as smooth is because it doesn't try to do too much - maybe the author has future plans for a full offline feature but right now I don't believe this is possible.
May I make a suggestion... have you tried InstaPaper FREE - I love the speed and simplicity of Reeder, from the blurb I just hit the Instapaper icon and before going offline anywhere I let InstaPaper grab the FULL web pages for offline viewing just as you do with Byline.
I honestly believe you are better off having these smaller, leaner, faster apps doing specific tasks, Reeder plus InstaPaper is the best combination you can possible have if you want my personal opinion, I've tried many readers and offline solutions.
I bought the even better InstaPaper Pro, worth it for the extra features and to support continued development if you use it everyday like I do.
Also have ReadItLater app as well - possibly as good as Instapaper and Reeder can send to this as well.
I think you'll find a perfect offline solution utilising Reeder and Instapaper to the best of their individual abilities rather than have one more bloated app trying to do too many things to please everyone if you know what I mean.
Hope this helps.
