This so far has felt really fantastic to use, great job guys! The amount of doors that this opens already is really incredible, it's hard to think about just how useful this will be!
Not sure if it's been suggested already but given that, abstractly - the UI (and presumably the underlying implementation in the runtime) that's been built for this maps from one value range to another + the ability to clamp on either end, it would be incredible to have the ability to map any of these properties in the same manner but to the color channels / opacity on a set of slots.
Not necessarily on the transform constraint itself - maybe a separate constraint? dunno!
Same UI but with source being a bone with targets being a set of slots, and the same source properties Rotation, Translate X, etc.. just mapping to the targets H/S/V/R/G/B/A channels separately with the same Options as well.
Just my two cents from fiddling around with this for the past couple days - the power that I gain with these transform constraints makes me giddy, but I then get put down at needing to run back and manually key opacity/color changes for the otherwise totally automated bits of some of the rigs I've been fiddling with. In my eyes that's the biggest missing link to having a really powerful suite of tools to build out controllers to manage complex transitions between poses and a huge variety of other things!
