I just tested your CubeDesigner. Generally, it is a great improvement having a graphical tool to create a mondrian schema.
But if I understood the philosophy of your CubeDesigner correctly, it does neither support
* the maintenance of Mondrian xml-Schemata (Cubes designed without CubeDesigner)
nor it is possible to maintain Cubes build with CubeDesigner.
Sorry to ask, but what is the intention of this tool if you can only use it for the initial definition of your mondrian schema?

Please do not understand me wrong, Pentaho is a good product and the idea of a graphical CubeDesigner really is a good one.

Will the tool provide the opportunity to maintain existing schemas in the near future?
Kind regards,
