Welcome to NORMA.
We haven't yet included the UUID datatype, but we should eventually do so. This is a little harder than, say, bigint because not all generation targets support it. Also, we've currently built the autoincrement and identifier notions into a datatype, when in fact the notion of datatype and autogeneration need to be separated. We'll evaluate the cost of adding this next week, hopefully it won't be worse than tinyint (a recent addition).
To change the column capitalization, open the 'Name Generation Settings' branch in the ORM Model Browser (Ctrl-W, Ctrl-M from the designer, or on the context menu), find the relational branch, then Column Specific. You'll see casing options in the Properties Window. Change it from the default (Camel) to Pascal.
