How do I know which Stack I am viewing?
Regardless of which Stack Category you are working within, when you are viewing the Stack Detail Page the name of the Stack is located at the top.
If you are within the Working Category, (active) is located below the Stack name.
If you are within the Shared w/Me Category, edit is not located in the upper right corner, because the Stack was shared with you and you cannot modify the master copy.
1. Working Stack
Active is below the name of the Stack which indicates you are within the Working Category.
2. Saved or Sent Stack
3. Shared Stack
Edit is missing from the upper right corner indicating you are within the Shared Category.
