It would be nice to be able to control a spectre while using a spectre bound spyglass, whether it be by default or (more preferably) after giving it a specific item. My main reasoning for this suggestion is because its very easy to loose a spectre if you're planning to use it out in the world. Being able to control one would ease the headache of getting it back in its bottle or on a leash, but also make them slightly more useful.

Alternatively, if outright controlling one is a bit too op, being able to tame one instead would also be appreciated, since it would be able to follow you around.
