FileMaker 14 comes with 140 professionally designed button icons that cover a wide variety of tasks.
You are able to change the colour and apply conditional formatting to the icons.
However depending on your task or application the right button icon might not be part of the preinstalled icon pack.
Don’t worry, FileMaker allows you to import new button icons to your solutions.
