I'm from Curious.com, and i found that I wanted to have a hide callback in addition to the show callback that you guys already provide in your feedback widget. I considered calling it "onhide", but changed it to "beforehide", because i figured it would be more useful to run the callback before everything gets destroyed, and might as well be clear about that behavior.
Would love to see this get pulled in. Let me know if you have any questions or if there's anything else i can do.
adding beforehide as an option
I'm currently working on planbox, does this callback still makes sense for you?
