Feature Request: See set alerts

[corpetty]

I'd like to be able to see what alerts I've set, and if I can't set more than one of them at a time (not obvious at this point), I'd like to be able to do that.

This would require some re-authoring which I'm happy to do at some point when I have more time. In the meantime, I do accept Pull requests :)
