Ratings and Reviews
Please DO NOT update!
Dear Liner, kindly please do not update your good app. The recent update to 3 has unfortunately messed up every good function you built. It now doesn't work properly in iPad Pro, iPad Air or iPad 2. Performance has downgraded from 9 to 0. Unstable is one thing, removing Evernote icon to enable exporting entire page of highlights is the most tragic move. Now each highlight must be individually exported. If you could just go back to the previous version, you would do the greatest job to make it great again! Otherwise, you are pushing the users back to the only choice for highlighting web pages to Diigo! Hope you would accept this advice.

The whole purpose of highlighting the content is lost and there is no way I can highlight a content easily on a smartphone. I am lost in finding the core feature. It would be good to simplify the highlighter.
