Hi @DeadApe and thanks for the kind words.
We don't have any ETA yet but our new web version is already in private beta. We're working hard on making it as smooth as possible before launching it and a Desktop version will follow that. We'll make sure to keep you all in the loop here.
Major-version updates will have an additional cost indeed, please find the details on this page.
We're here if you need anything else. Enjoy your day!
