I would like to formally request the most basic documentation: for properties that can accept a range of values, can we get the upper and lower limits documented at the least in the class code? I’m assuming most things are on a 0 to 1 scale, but it’s just a guess and I often find myself wasting time checking if the upper limit is 100 (as in percent) since there’s no way to know

Formal requests should be posted on GitHub. A forum is not a good place to request features/documentation, because your request will disappear with time in the flood of other questions.

If you are wondering about any particular property, please ask.
