Yes, a very good add-on.

Advantages: very nice look, well structured, easy access, quick RSS search, drag and drop functionality, avoid duplicates if the user doesn't want to, different and very friendly news display modes (list, content and in place web content), avoid multiple tabs and windows in the browser by using a very functional popup window, make used of a save search. Just Amazing.

Disadvantages: Not included in the tools menu, not included to add feed to a given group but you have to add first to the default location and later drag and drop the feed to the desired group.

Conclusions: The advantages overcomes the disadvantages but a new update with the disadvantage features implemented would make this add-on one of the top rated.

My rate: 4.8 stars

I'm glad you like this add-on, thanks for the review.

"Not included in the tools menu"
The menu will be present in the next version.

"not included to add feed to a given group but you have to add first to the default location and later drag and drop the feed to the desired group"
I thought about it and seen that the choice of group is the last step this way is the fastest way to add a feed.
Even if you change the group drag and drop is faster than selecting in a tree for example.
