**1. Description of the problem that is addressed in the patch.**
The current method for updating a Pose is not obvious to users, especially beginners, as the "Assign Action" method does not imply Pose Asset editing unless the user is well-versed in the Action data-block workings of Blender animation. It is also not available in the 3D View's Animation Panel or context-menu which makes such a valuable feature undiscoverable. The title can be confusing as the asset is called a Pose, but the operator is called Action. To edit an action, the user must also know to create keyframes for all edited bones which is not clear. Further, the Overwriting-a-Pose feature is available in several major Pose Libraries and arguably expected by an animator in the primary user interface.
**2. Description of the proposed solution, and a motivation as to why this is the best solution.**
The Update Pose feature surfaces a Pose overwriting operator to the primary user interfaces in the Context Menu and Asset Library respectively. Its name includes Pose so the operation has more obvious expectations to the user. It is also a faster, more intuitive solution as it does not require the user to key all edited bones: the operator has an option for reselected the original pose’s before automatically keying them on creation.
**3. List of alternative solutions, and a motivation as to why these are undesirable.**
Another solution could be renaming ‘Assign Action’ to ‘Edit Pose’ and adding it to the Pose Library’s main UI & Context Menu, but the issue of multiple steps (and likelihood of omitting a bone reselection from the original pose) remains.
**4. Limitations of the proposed solution.**
The proposed solution does not edit the existing Pose data, but overwrites it. This overwrites the thumbnail image preview (undesired when using a custom Pose preview image) and can potentially introduce confusion/bugs of the previous & new Asset in memory if not carefully handled in the code.
**5. Mock-up of the proposed user interface and a description of how users are going to interact with the new feature.**
Users can edit a pose by Applying the pose, adjusting the bones, then choosing ‘Update Pose’ from the Context Menu or ‘Update’ from the Pose Library Panels in the Asset Browser.
