I'll just add it in, it shouldn't be hard.
If it is OK, I'll just show the numbers instead of text with them. There are currently two fields (length and scale) that are basically placeholders and appear with different names in the properties window (length becomes precision for Money and Decimal types). Translating those names into verbalization snippets (which pull strings from a totally different and much more configurable source than the resource files) is more involved than I have time to get right now, so you'll just see numbers like (10) or (13, 5) at the end of the text. A length of 0 translates to MAX in the relational mappings, but I'm not going to try any data transformation here. You'll just see (0).
'Portable data type' is not a name we display anywhere else, so I'm changing this to 'Data Type:' to match other verbalization strings (like 'Reference Mode:'). Also, if an entity type has a resolved reference mode then its identifier also resolves to a single data type, so I'll go ahead and show the data type as well. This will give you the information without expanding reference modes, which is a hassle.
Let me know if there are any objections and I'll put this in the next release on the NORMAPreview page.
