The new Explorer of ObjectDB 2 is currently a viewer rather than an editor.
It always opens databases in a read only mode.
The Explorer should support creating and storing new database objects and editing and updating existing database objects, visually, with no code.
This is one of the features that have been supported by the old Explorer of ObjectDB 1.
It has been temporarily removed due to incompatibility with the new ObjectDB 2 code base.
