Good lord, why are users of free software always act so entitled towards developers they have paid not a single cent to? Just "simply" port your native GUI application to a completely different platform and make sure everything works as intended. No biggie! At least donate a couple hundred dollars to the developer so he can afford to run a couple of Claudes before you start asking for things.
