Thank you for your post.
Neither the HTML nor XML Database Design Report lists the Theme count in either FileMaker Pro 13 or FileMaker Pro 14. Therefore, I recommend entering this as a suggestion into our Feature Requests web form at:
The entries into this web form populate a database file that is hosted and monitored by Product Management and Development. All entries are read, discussed and considered for possible implementation in a future release. Although I do have the ability to copy your post and paste it into the web form, there are a couple of questions asked on the form that only you can answer.
thanks for the confirmation. I've made a feature request.
