Howdy! I do not have any plans for updates at the moment but surely at some point. I guess I could consider opening the repository for you if you're serious about making contributions. Makes more sense to publish the chances to everyone if you manage to make some real fixes or additions. It gonna be nicer to dig around in the actual source code too instead of the compiled raw javascript too. 😅
Hit me up on Discord (anttihaavikko) or email (antti.haavikko@gmail.com) if you wanna get in touch.
