If it’s not allowed, why doesn’t Envato disable purchase button from author’s file? I think 1 purchase should be fine.
Paypay, not yet.
Edit: Sorry, I haven’t checked mail yet, I’ve received for 2 hours. Thanks Envato.
Don’t afraid to say no as well. You will have buyers who want customization (rather than bug fixes/adjustments) and you should have a distinct line where too much is too much. Otherwise you’ll be spending all your time providing free valuable development hours – not support hours.
I’m a newbie. When some customer wants something, I’ll consider it and question myself: “Do other customers need this feature?” If it’s very specific, I’ll refuse. If it’s general, I’ll update the theme. I can also learn so much from developing new features.
