do you mean to copy mapper settings to another game? Currently can be done with profile duplication which is not very suitable if you have already styled game.
Second, better way is copy mapper.xml from first game to second manually.
I will add something like “clipboard” (or something similar) in one update. This allows to copy widgets between layouts. The same I can do for mapper. I want add this feature to version 25-28. Depends on other things.
Probably today will go out version 23. Version 24 is done, but is strongly tested, because there were many core changes. Was added longpress and double tap, also keyboard and mouse handling was rewritten too. There are big background changes.
