The most helpful feature that I like is detailed font preview and Organizing fonts when I'm working with multiple projects also I'm fan of font troubleshooting feature such as corrupt font file issue

It's an extensive font management, you can organise your fonts into the right group and collections, effectively creating a large and organised library. The Preview function is also very handy to make your workflow faster.

1. Font library is super useful 2. Helps in detecting font errors 3. Windows shell extension is of great use
