- Added support for using a curve to map from input range to output range - Added compilation warnings when a bone or component still needs to be selected - Added a customization to hide the range/multipler when using a curve, and gated editing of the range based on bUseRange - Minor optimization to evaluation speed - Reorganized the properties into logical groups (Source/Driver, Mapping, Destination/Driven) [CL 2591125 by Michael Noland in Main branch]
