Adding a "spectrogram" poll type

[gerhard (Gerhard Schlager)]

having something like the number poll type with a min of -100 and a max of 100?

I like the idea of spectrograms, but (without listening to that talk or reading anything about it) do we really need 200 choices (-100 to 100)? I guess -/+5 (or maybe -/+10) should be enough.

@lidel

perhaps <input type=“range” (..)

Please don’t. Numeric sliders have such a bad UX most of the time. Imagine you have a large range like -100 to 100. Try selecting 76. Good luck! In that case a numeric input is way better. And when you have only a few options, it’s easier to just select the option by clicking on a button.
