Applies to:DM Language
Status: Not Feasible
Implementing this feature is not possible now or in the foreseeable future
Suggestion:
To add a unique ID to each overlay making overlays a list of current overlays.

overlays+=image(icon,icon_state = state)


is not removable unless you do...

overlays-=image(icon,icon_state = state)


What happens if you lose the icon though? You're doomed to an eternity of having that overlay.
So my suggestion is like so...

RemoveOverlay()
        var/T = input("Which overlay would you like to remove?") in overlays+"Cancel"
        if(T=="Cancel") return
        overlays-=T


Where T would be a numerical-text type thing according to when it was added on.

overlays+=... = overlays+="1"
5 later...
overlays+=... = overlays+="6"

When using Remove Overlays it would show the options to remove... "1", "2", "3", "4", "5", "6"
and so on.. I suck at explaining things, I just try to throw as much of my idea out there as I can and hope you understand.

This is not doable, but a simple workaround is to take the just-added overlay from the list (you need the actual item in the list, not what you added) and store a copy of that in a var somewhere.
