I agree. Great suggestion!
A related request: When we add a child to a parent who had multiple spouses, there's a series of checkboxes to identify the child's other parent. That list shows only First Names and Current Last Names -- no LNAB and no WikiTree ID. Particularly when a man had several wives with the same first name, this can make it very difficult to figure out which one to choose. (If I'm adding a child for Lewis Jones, I am asked if I want the mother to be Elizabeth Jones or Elizabeth Jones or Elizabeth Jones, but I want to select the Elizabeth with a particular maiden name.) It would be real nice to include either or both LNAB or WikiTree ID in those displays.
