In Context (posts and pages) notes that is readable only by admins/moderators

Hey!

I want to be able to add notes on the page/post itself, among the text, that only I can read. Not anyone.

To make it simple: I have a queue list of commissions and not everyone want to be open about their contact information so I want it to be like this:

1. April ([email protected])
2. HH ([email protected])
4. DLee ([email protected])

So the list will be visible like

1. April
2. HH
3. DLee

to the public. So I can easily see the contact address in one and same place, but the public won’t see the sensitive information.

I have found a plugin here:
https://www.ads-software.com/extend/plugins/in-context-admin-notes/

But its disclaimers AND it being abandoned (long time ago it got updates AND it has low feedback grade made me unsure.

Do you know of something suitable and more reliable for me? THANKS!!!
