Yea I understand your frustration, there are probably more rewarding projects to work on instead, for me too.
Imagine yourself releasing a program for sale and then having 2 people copy the same idea within 1 week, one of them releasing it for free.
The 0.3 sec/name ESTIMATION is for a FUTURE version, not the one for sale now. It would be given for free to existing customers, though.
I was gonna make that name checker, but I had exams. When I saw you selling one for 30m GP, I was like what? Cause I was gonna make it after exams, and sell it for 5m GP, since it was 30min-1hour work for me roughly.
