In FileMaker you have the option of showing sample data in fields when you work on a form. This means that you can check font sizes, colours and formatting in layout mode.
Showing sample data in desing mode is on our planning
Great.
One other problem I’m encountering is that objects have no boundaries (or outline) when working in design mode (at least in my forms!), so I have to temporarily set the background to some bright colour to see what I’m doing.
FileMaker has “show field boundaries” and “show text boundaries” under view–>show.
What about an option in design mode to simply show the outline of objects that don’t already have an outline? And make sure the setting is global for all forms, rather than specific for each individual form.
