Hello! Adding a checkbox in the Photoshop export script panel to align the origin (0,0) to the center of the canvas during export is a feasible idea. The script can be modified to include this functionality, and it has been suggested that features like this could be added as checkboxes if they become commonly used. You can modify the script to include this feature by adjusting the canvas alignment code, or if you're not comfortable with scripting, you might need to wait for an official update that includes such a feature.
