animation tools: motion path which allow to direct tweak curve in view port for better animation arc, improve view port perfomance because when enabling onion skinning the perfomance become very slow, drawing tools like doodle.
rigging tools: autorig with facial controls.
modeling tools: bridge tool improvement the current workflow of selecting the source edge/polygon and the selecting the destination edge/polygon it's real boring and time consuming, hope the improve this by allowing selecting both edge/polygon and apply bridge.
edge loop tool need improvement to allow symmetry adding two edge direct to the conner of the object, this will increase speed in modeling process like modo loop slice has many functions (symmetry ,free, uniform).
grooming: improve the perfomance when applying the hair gen it's like simulating ocean on my laptop the perfomance become very slow. due to this it's real hard to make grooming process hope the sideFX improve the perfomance of hair and fur tools.
