I found it.
Writing my own plugin. I really hate the developers who modify the user experience to ask for a donation. Open source is a philosophy and yes, you can insist on a donation from time to time, or using a LESS invasive strategy. Inserts ads about your pro version on the plugins list is not professional, you are breaking the purpose of this area. Modifying the footer is not a good design idea. If all the plugin writers do the same … mmmm …
If you write something expecting to receive some donations, you cannot treat your “customers” in this way, please use your shirt too. Your plugin is very good, but some users are not comfortably when the piece of code modify the behavior of the admin software too and is not necessary, settings page is ok, but no more. Please specify that on your plugin description, admin and blog areas will be affected.
Read about design, user experience, etc. Donations arrive when you make a good work and the users recognize your efforts, and not for bug customers/users. Respect the people that is using your software please.
Some examples to learn:
Efficient Related Posts. https://xavisys.com/wordpress-plugins/efficient-related-posts/
They include a panel about their company with news, on the dashboard, very simple, logo and the info. That’s all, no more of that. On the plugin settings page, a link for donations and a lot of useful information and links.
Akismet. Well known. Whe you ask for the API key, they put the money issue if a commercial use, or ask for a donation if not, that’s all. The user don’t have to show the request for a donation every time.
All in One SEO. All the action is on the settings page.
XML Sitemap Generator for WordPress. On settings a note about donations, and a ” No thanks, please don’t bug me anymore!” link ??
Note:
This is a constructive comment. Take it or not, your desicion. But treat people with respect, even if you think is funny. People is who donate.
bye.
