I have been using iClone for about 4 years and have worked extensively with it. I would like to share some suggestions that could make the process more fluid, at least for me. Here is the list:

Complete Timeline Bake with Clip Separation: Allow a complete bake of the timeline while maintaining the separation of clips without merging the entire timeline. Additionally, provide an option to bake only a specific clip.

Return Root Bone to Character: Sometimes the root bone can be accidentally displaced. It would be helpful to have an option to return the root bone to its original position beneath the character, centered. This option should be different from the existing ones that place the root bone at the hips, xy, or xyz.

Zoom in Timeline at Playhead: Enable zooming in the timeline exactly where the playhead is positioned.

Automatic Pose Copy-Paste Between Characters: Improve the process of copying and pasting poses between characters. Instead of selecting a character, copying the pose, selecting the target character, opening the command again, going to the pose transfer tab, and pasting the pose, make this process more automated.

Batch Rename Clips: Allow the renaming of multiple clips simultaneously.

Cut Clips in Multiple Parts Simultaneously: Provide the ability to cut clips into several parts at the same time.

Onion Skinning: Implement onion skinning to better visualize motion between frames.

Joint Motion Path: Introduce a feature to display the motion path of joints.

Natural Idle Motion System: Create a feature that applies natural idle movements to the character’s joints, regardless of the pose. This system would add subtle motions to joints, enhancing the realism of keyframe animations.

Spline Rig Controller: Introduce a spline rig controller for more advanced animation control.

Smooth Timeline Scrolling: Improve the scrolling in the timeline to be smoother. Currently, it is very jerky. Programs like Unreal Engine or Adobe Premiere have very smooth timeline scrolling with SHIFT key, which could serve as good references.

Delete All Undo-Redo History: Provide an option to delete the entire undo-redo history to reduce the file size.

Interface Color Customization: Allow users to change the interface colors of iClone. This is a feature I have wanted for a long time.
