Real-Time PlayMode Preview

Animation results often differ between Edit Mode and PlayMode due to factors like IK, layer blending, and lossy frames. Currently, assigning a rig in PlayMode instantly resets the skeleton to the animation's current frame before any scrubbing, which diminishes the utility of PlayMode editing for features that modify the final pose, like IK.

Would it be possible to allow users to edit the rig on a paused frame without the skeleton resetting? I am using a single frame animation which is applied and it would be handy to adjust the spine rotation in realtime and then export the result.

Is a similar feature already available, or is this too complex? Thank you for considering this enhancement.
