I've had this app installed on my phone for, well, I guess 3 years as that's when it came out. The lack of posts in this thread suggests everyone finds it simple to install and use, and it does exactly what it says it will. That's a pretty impressive feat for any piece of software!
One thing that's always puzzled me, however, is that it doesn't offer notifications when new content is available. I must have missed 100s of interesting posts during that time purely because I didn't know they were there to be read!
Have you thought about doing an update to include notifications?
Or, a horrible thought has just occurred to me, does it already support them and I have somehow got it configured wrong?!
