Can a Renoise Tool also contain the KeyBindings.xml so that they are easily imported?

Is there a way I could save KeyBindings.xml inside the Tool folder so that it would be easy to load it into Renoise Keys?

well, yes kinda. you can just have the xml there inside the script. but the writing you should do either yourself, or make it into a wild destructive script that runs an external script to overwrite KeyBindings.xml… that’s difficult.
