It’s been awhile since I’ve seen it, but I believe that TDM2 had a tool that would permit me to browse all the attributes from all the tables in a single list. As I recal the list of attributes could be sorted by table, attribute name (column name), and probably other fields also.
It “feels” like this should be available in TDM3 on the Model menu, where I see “Entities, Relationships, etc.”.
Is this available somewhere in TDM3 already and I am missing it? Is this planned for later?
