Perhaps a change in the type of production would be necessary ala Scrum etc., i.e. a few (1-2) features fully implemented in an I think broad-minded alpha test group with a mandatory feedback circle and then a stable beta every 1-2 months with this features (but not with all features), so that people don't lose interest in this genius sprite animation tool - I know the Alpha testing tool exists, but less features and a limited mandatory testing group would probably make sense. Otherwise the developers feel obliged to keep adding more and more features. - and a PayPal-Donation Button to push the development
