This is just something I was curious about. Why is the feature to unhide all layers a plug-in and not built into Synfig? Is it a feature best left as a plug-in? or maybe it’s planned to be built into Synfig but not implemented yet?
it is a bit complicated to add new hardcoded features and plugins can be developped/modified quicker.
I think it could be done for this example, but the purpose is to be a demo for this possibilty.
Plugins modify xml files directly, not through the application as embedded script.
