Add ternary choice "maybe/dunno" about jawanndenn

I thought there was a ticket for that but I cannot find it. I agree that would be nice to have as an option.

It's a tough challenge with regards to usability and also implementation. Either you need a tristate-checkbox which is a can of worms of its own (e.g. Dogfalo/materialize#3875 for what I wanted to be sexy enough, the what color has that third state, what to do with keypresses) or you need multiple controls (say radio "buttons") or make your own altogether. Plus all of that makes the interface more complex. So I'm really not sure what to do about that.

Yeah, I agree with you. I've tried implementing it (bagage@8c8e0cf), but it's somewhat not super clean. (I had to remove filled-in class for instance, as you stated on materialize issue - not a big deal for me though).
But since I needed it for a project, it might be a starting point for you at least :).

@bagage looks like you made a lot of improvements in your branch -- would you consider submitting some PR's back to this project?

@stackedsax sorry I stopped used it. Feel free to do so if you think it's valuable!
