I have a FM solution that I would like to use the theme for in another database. Is there a way to export the theme from one to import into another?
Other way around. You go to the database without the theme, then import the theme from the database that has the theme.
How to import a user created theme from one FileMaker Pro file to another FileMaker Pro file | FileMaker
I actually have a file that I use just for storing themes. I have a few layouts with common UI elements on it in that file to make it easy to preview the theme. Then I import from that file into the files I work on.
+1 on johnnyb's approach. Using a "sandbox" file to develop your themes will help maintain some discipline in theme design. Combined with a well thought out style naming system, it gets a lot easier to import themes and apply them to existing (or new) layouts. Alternatively, for a bigger project, you could also use a dedicated sandbox layout right within your UI file.
That is really helpful!
