Yes! I also want this app to become available on Flathub. It would be much more convenient to use it. I guess the app developers should be involved in order to make this possible. But if they're as open-minded as those from https://smartengines.com/, it would be great! I appreciate when app developers listen to the feedback of their costumers. It helps them become better and better. It's a convenient way to interact with your costumers and to fix issues at the same time.
