It’s a very interesting application and you did a good work. Could you pls open a new repos on github ? You will be able to work with the community to improve your package and to get suggestion. You will be able to have test from the CI jenkins to review your app too.
If you don’t have a github account, you can create one, and I can add you to the Yunohost-Apps organization. You will be able to create a repos directly in Yunohost-Apps orga which is the place where there are every packages from apps.
