Hi,
you can export workspaces and import them. It’s not possible to save standalone panels. The third party has to own Configurator Reloaded to be able to import workspaces.
It will work for actions if the third party install them with the exactly same name of the set and the action. Remember that some actions will only work if the third party uses the same language of Photoshop.
Script buttons link as a path to the script. So it maybe will not work if the other person has the script file on a different path.
