In the previous section we’ve seen how to create simple scripts to do things to fonts and glyphs. These scripts had no user interface – if we wanted to change a setting or a value, we would have to modify them directly in the code.

In this section we’ll see how to create interfaces for our scripts using vanillaA Python library for creating native macOS user interfaces..

An interface is useful when a tool is used very often, or when you are building tools for others. Rather than changing settings and values directly in the code, we can offer the user a window with visual controls: for example checkboxes for selecting options, input fields or sliders to adjust values, button to apply actions, etc.
