I found this statement in one of the FileMaker links regarding custom themes.
"While you can modify layouts, it is not possible in FileMaker Pro 12 to modify and save a theme. We realize that you may want to create custom themes to use within your databases or to share with others. We may consider such a feature in the future."
I don't want to beleve this - surely FM doesn't expect data designers/developers to be trapped inside of such a limitation as only 40 very similar themes. WHAT!! FileMaker "May consider such a feature in the future"
How do I customize add 15 navigation buttons to apperar on a theme?
