NvEZOS is really really good. Easy-to-use. I think you spent so much time to make it. Ubuntu is an open-source project, but you make it different.

You must require "license" after 30 days trial usage. Or you can require "buy addons". (Basic settings is free, overclock section is for 5 USD, simple rig reser section is for 5 USD etc.)

If you get paid, you develop the NvEZOS. Of course, every developer wants to make a good profit.
