This is a great plugin. Thank you for that.
You have a donate button on the Settings page, however the Donate button is very annoying on the Edit pages.
There is no way to see for end users to whom that Donate button belongs to, they may think that the Site Admins want some money from them.
It's makes difficult to maintain the consistency with other admin Edit pages. Please remove the Donate button from the Edit pages. Otherwise the admins have to to modify the core files to take remove it.
