Treat your users with MBS Plugin
While the normal users of your solutions don't enjoy syntax coloring as they don't edit scripts, they may still enjoy our benefits in same places like the search feature in the export dialog.
The tooltips in the export dialog tell them the field type so they can identify calculated or container fields easily.
Tell your users to install MBS Plugin, even if they don't use any of the functions and just enjoy the search feature. And if one of your users comes to a FileMaker dialog with a list of items, they may use our context menu commands to copy the list of values shown there.
