I guess it’s OK if you aren’t a power user. No access to Apple or 3rd Party extensions.

Be prepared for two steps everytime you want to share something outside of the most basic. Want to send to omnifocus? must open in a browser first. want to e-mail the article? nope. only links can be shared. It is inexplicable that there is NO access to third pary extensions or even Apple extensions. So you won’t be sharing articles to Notes, 2do, DayOne, Dropbox, OneNote, etc. even though these extensions are sitting right in your mac ready to be used. It’s a shame that in the year 2017, we still have only two RSS readers that barely offer any power user options. This one and the unsupported Reeder. Every RSS reader designer should be forced to study Newsrack, which in 2011 was 10x as powerful as both Readkit and Reeder. If you want five stars, it’s very simple: Quit locking down your share services and at least include the use of apple and third party extensions!
