How’s it going? I understand your idea. And well, I really wouldn’t know what to tell you, it will depend a lot on how many things it replaces in the system you use. But we’d have to test it to be sure... I’ll propose something.
Let’s do it the other way around: contact me by Private Message (from my support page) and attach your email so I can send you a download link for the plugin so you can test it. If you see that it works correctly, let me know and then proceed to purchase it normally.
Does that sound good?
