A variable font preview slider would be amazing, letting me adjust weight, width, and slant axes right inside the app to see how the type handles different settings before I commit to using it.
Tried it for a bit and the preview feature is genuinely fast. Hovering over a font and seeing it applied instantly across a sample text saved me so much time compared to my usual workflow.
