Dear IEF developers and users, I am wondering, why the single value inline entity form widget does not support the selection of existing entities? In my project requirement, the user should be able to choose if he want to use an existing entity or create a new one. I -could- use the multi value field and limit it to only 1 value, but this is ugly in user experience perspective: "You have added 0 out of 1 allowed" is a useless information The draggable list of values is also useless, we only have one possibility

I suppose this has no security implications.
