Tickles.

Hi, I'd like to tackle this one, I've been working on a basic implementation but have some questions about best practices and such, what is the best place for this?

I've started a new PR with my first attempt at implementation and a bunch of questions.

Hi, I'd like to attempt this one as well, the design seems a bit more fleshed out so it should provide some guidance for the other pull request as well.

Should this be developed against 2.2-develop or 2.3-develop?
