I've found a couple of useful replacements for the default text widget that allow the widget title to become a link (eg the "Linkable Title Html and Php Widget").
It would be great to have this functionality. Would you consider adding a "Title URL" field as a feature?
Or could I hack the widget to remove the filtering out of anchor tags from the title?
(I know this adds the danger that somebody could seriously break things, so you presumably wouldn't want this as a feature.)
cheers, Steve W.
