Does exactly what I want and no extra jazz
Makes it easy to spot some articles just by scanning for an highlighted word.
I bought multiple years of "Supporter" level while it was cheap and some features I like were moved into a more expensive tier, and I'm glad I did because the features are grandfathered in until I need to renew.
This thing is packed with features, yet simple to use. Not only is it the best RSS reader I've ever used, it's up there in the top 10 of all software, of any kind, I've ever used.
The only feature that I would like it per-folder scan tracking (Mark items as read when you scroll past them). It is currently system wide based on the View types (magazine, list, etc.)
Used TheOldReader.com when Google killed Reader, then switched to inoreader. Haven't looked back (even though I'm using the free version still).
edit: Adding that I find the android app to be of excellent quality.
