Turn Widget titles into directory links

[boonebgorges]

The Groups and Members widgets ought to have their title link to the corresponding directories. The only thing is that then they'll have link styles; my attached patch undoes these styles, so that you can't really tell they're links.

Any objections to doing this?

I kinda object to this. It should be up to site owners if they want the widget title linked to the component directories.

I would suggest filtering the title and adding actions so devs can modify the widget output.

If we want to add more options for end-users, then perhaps add additional widget options?

Thanks for pushing back on this one, r-a-y. On reflection, I think you're right.

I was hoping to avoid adding more widget options, but to be honest, this one seems like a no-brainer. I'd think that lots of people would like this option, and wouldn't want to have to deregister and reregister the entire widget (or write a filter, for that matter) to get it. So I'm going to go ahead and do it :)
