Is there an existing proposal for this?

• I did not find any existing requests.

Explain your idea

When a conduit probe copies an item, display the data that is copied in the tooltip of the conduit.

I will try to include this in #1126 for 1.21.1 and hopefully also backport to 1.20.1 in another PR.

Why do you thing this feature belongs in Ender IO.

This allows the currently quite opaque copy/paste feature on the conduit probe to be more easily understood and prevent copy/pasting the wrong things on accident.

Are there any alternatives?

Add the information to the chat when a conduit is copied instead (or add to chat alongside with adding to the tooltip)
This may be better because a conduit bundle could quickly have a lot of data to copy (item+fluid+energy could have up to 15 pieces of information already)

Any Additional Information?

An example of something similar is the Gregtech Machine Memory Card (image from Monifactory)

Since item conduits can have many properties and the tooltip will probably look really bad if it is too long (for example, a fluid conduit has up to seven settings to save), I think the best option would be to print whatever data was copied to the player's chat, and then show the types of conduits that have been saved in the probe's tooltip for reference.

That sounds sensible to me
