I know the plugin you share is more advanced. You misunderstood me.
When I opened the topic, I did not know how to develop/edit a plugin in IPBoard. After opening this topic, I learned developer tools and edited the plugin.
I couldn't ask for permission because the developer didn't reply my question on the plugin page.
I have no bad purpose, I just wanted to share it for everyone to use. Now I will develop and share my own paid and free plugins. Because I love IPB. 🙂 I have been using IPB for about 3-4 years.
