The need for better interaction with MS products. Arcmap could read/show Access .mdb files without a configured OLE DB connection. Wouldn't it be more intuitive to be able to do the same with Access .accdb files? Having to connect by creating new OLE DB connections for each Access db gets to be a bit redundant. So a direct read of these databases would be much more useful to us! Or am I just missing something?
