Describe the feature

Enable users to bookmark items, fluids, and similar elements from the GUI into EMI's bookmarks while viewing recipes, just like in JEI.

Reasons why it should be considered

Because I want to be able to bookmark items on this interface, allowing me to more conveniently create templates or design production lines—rather than relying on memory or notebooks—ultimately leading to a smoother gameplay experience.

EMI isn't supported on 1.20.1

tho I think most things should work if you install JEI alongside EMI.

At least add this feature in version 1.21.1.

it should already work in 1.21.1.
if it doesn't please open a bug report

I've already submitted the issue – please check:
