I was thinking about how to visually show some of the 'clamps' or limits because often the constraints becomes kinda trial and error to get the right values (oh, the control is rotated 90 degrees so translate X (left right) becomes Y (up down) etc).
Something like this (the yellow line/box) would be super useful especially for setting up control rigs. They do this in things like blender etc.
^ A little checkbox by the clamps.
^ Translate X clamps shown visually in the viewport (with yellow line)
^ Translate X and Y clamps shown visually in the viewport (with yellow square).
Somehow showing a 'ghost' of what the effect would be on the resulting bone would also be incredible. Maybe as you roll over each constraint value it would show the min/max result in the viewport as a ghost.
PS.Would also LOVE alpha/constraints (ie rotation or translation to control opacity). Would be incredibly useful for asset swaps like hand poses. So happy to see someone else suggest that and that it's something you are looking at!
A slider is a type of constraint that applies an animation. This is useful for all kinds of things. For example, you can use an animation with a bunch of attachment keys, then use the slider to choose which to use. You could also use a slider to apply poses or facial expressions -- anything you can key. Also, since you can animate the slider position, you can interpolate between adjacent poses.
