I would suggest adding the following improvements:
- Add the ability to create categories for feeds. Currently, it's Top 50 or My Sources. I like to categorize my feeds.
- Remove already read feeds and add a button to mark as read, mark all as read.
That's all for now... I would like to ditch Feedly and I'm thinking that it may be possible (at least for me) by having Opera sync my RSS feeds between PC and phone.
