           Summary: ER diagrams need to underline the attribute name of
                    primary keys
           Product: umbrello
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel.kde.org
        ReportedBy: kretz kde org


Version:           unknown (using KDE 3.5.0, Kubuntu Package 4:3.5.0-0ubuntu0breezy1 breezy)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.12-10-686

The classical way to draw ER diagrams shows attributes as ellipses with primary keys underlined. To make sense of an ER diagram it is often necessary to see which attributes are primary keys.
Umbrello's ER diagrams don't mark primary keys at all. Other programs show a key next to the attribute name, which would solve the problem as well.
I'd suggest to just show the primary key attribute names underlined.

Patch follows.
