Thank you for the cool mod!
But I don't understand how to use the quick panel — ghosts are not taken in hand. Only through inventory or pipette.
Please explain how to use the quick access toolbar.

I don't know. :-) I will have to look at this. I didn't write this mod, I just revived it. And while I do know something about programming, I haven't looked at this mod in detail.

Enable "Pick ghost item..." in the Interaction section of Interface settings.

Thanks! I didn't encounter this problem in the vanilla game, so I thought it was because of the mod. )

I believe the mod used to do it. The mod dates back to 0.16. I think the code was ripped out when vanilla grew that feature. I feel slightly embarrassed that I didn't realize what the fix would likely be myself.
