Thanks for contributing a great module this has helped me immensily.

I just wanted to point out a usability item that might be worth thinking about at least. I keep forgetting to select the "Show this block only within the following groups:" mainly b/c I think I assume that if I check off a group for it to display in it should just work. I'm wondering if having the top checkbox is redundant in a way and maybe could be just added as a tip instead?

Thanks!
