How to define the current PAD Link as Icon in settings?

[lisandi]

How to set the current PAD Link in settings - which would be different from Pad to Pad - to open up externally

"ep_button_link": {
"buttons": [
{
"link": "https://example.com",
"text": "A button"
},
{
"link": "https://example.org",
"text": "Another button"
}
]
}

Another suggestion would be to have a checkbox to show the current pad as an external Icon (as an Icon) or a settings setting to SHOW/NOT SHOW that external icon of the current pad as a button, while defining other links in settings.

What would be the best way to define an icon - font awesome/image upload/image link?

to get rid of that message?
