A Materialized View is shown in two places in the Connection Tree:
- under the 'Tables' node and
- under the 'Materialized Views' node
Depending on the object node, the MView is being opened either in the Tables Object Viewer or in the MView Object Viewer.
It would be really nice to be able to open the MView in the MView Object Viewer although you are viewing it in the Tables subtree.
Maybe as an additional context menu entry?
