• Update on hover message for clarity.
• Remove "Click to disable this." when the button is disabled.

Enabled

Disabled

I think the same button showing different hint text depending on the context might be unexpected by many users. It could be harmonized into more precise language, for example:

This node can be accessed from within anywhere in its owning scene by preceding it with the '%s' prefix in a node path.

I do like this combined language, however I fear users may not understand what ownership really is, but maybe that's not the problem to try and solve.

Thoughts on?

This node can be accessed from anywhere within the scene it belongs to by using the '%' prefix in the node path.

I would also be just as happy if the message was the same and we at least removed the "Click to disable this" when disabled as it's not immediately clear why you can't click it.

I think the tooltip is a great place to mention what pressing the button does, because it isn’t really explained anywhere else what it does.

This is fine, actually.
