well, i'm right down the middle on rss ticker Puntuado con 3 de 5 estrellas
very good, does exactly what it says; i have no problem disabling the feed if i'm busy, or opening and closing items. normally this would rate a 5-star review.
what rates as 1 star, however, is the method of adding or deleting feeds from the ticker. i just moved all my google reader feeds [100+] over to live bookmarks in order to use brief and i had to click 'remove' for each. and. every. feed. i. added. sheesh.
what i would like to see in this addon is the ability to set a bookmarks folder from which the ticker could take its items. how about it, mr. finke? i promise to upgrade this review to 5 stars if you update the addon!
If you want to add or remove multiple feeds from the ticker at once, click on the first one you want to add/remove, then hold down the Shift key, and click on the last one. Then, click "Add" or "Remove." You can also hold down Control (or Command, on a Mac) to select multiple feeds that aren't next to each other in the list.
Hope this helps!
