UPDATED 5/12/19 - Added a checkbox which aborts the script at any point.
This script for Toon Boom Storyboard Pro allows users to consistently rename layers across multiple panels, regardless of their original name. Got a scene with too many "CHAR_1" and "CHAR_2" layers and just want them all to be renamed "CHAR?" No problem! This script will take care of that for you! Also, if you want to rename a layer to something that already exists in that panel, the script will make sure to rename that existing layer first, so you can still have your consistently named layers across your entire scene.
See the script in action via this YouTube tutorial video: https://www.youtube.com/watch?v=t9V8XgBIn5k
