Congratulations: you have really done a great job.
I did not understand what the button "sticky" (in italian appiccicoso??).
Can you explain its meaning?
Thank you very much
Saluti, Dino.

Salve Dino

"Sticky" - means that the feed marked as sticky will stay always at the top of the list[even if it's older or even if it's on the second, third, etc...page]
...something like the "sticky posts" on forums.

I'm not sure what the "appiccicoso" word means or if it's right...the italian translation was made by an italian guy.
If you think it's not corect just say and I'll change it.
