Hi! Nice work....
One thing that I find it might be very useful is to have a "title link" or a "read all" link at the end of the widget.
For example, I have "latest news" category in posts, with 3 latest posts showing in the widget.
But if reader wants to go to all posts, there's no link of some sort on the widget itself.
Thanks again and I'm looking towards your reply!
Cheers,
Bernard
