This plugin has a standard license. Legally, you can modify my plugin to use in your own projects, but you cannot sell modified versions of the plugin.
If you would like to collaborate to improve the tool for free, we can explore a way to do that.
Of course, you can use my plugin as inspiration to create your own, but it wouldn't be good practice to copy the code, in whole or in part, so the answer would be no. Thank you for your interest, feel free to ask anything!
