Hiya -
By going to the Attributes pane of any object type, I used to be able to see Attribute IDs for each Attribute. Now, the ID column is gone and there's no button to bring it back.
I feel like the product team made a change here that now makes using the API especially difficult. I don't want to query Attribute details via the API... the object format is particularly cumbersome. Why not just show it in the UI?
