Font search and activation
In the Creative Cloud app, fonts families appear with panels fully open. It annoys me to have to scroll! There should be the ability to collapse all fonts families at once instead of having to do it individually. Even better would be a way to search for a font in the app. The search field in the CC app searches for other things that take me to the Adobe website. I would to be able to search for a font and activate/deactivate it within the app without having to scroll to find it!

Not having a search function to filter fonts by name in 2025 using the CC app is like finding out your 32 year old son never learned how to swim.
Yes, you have a great selection of fonts, but using a clunky app during what should be a smooth creative process is such a headache. When I switch from Fontbase to CC I feel like I've traveled back in time.
Not to mention the lack of convenience of not being able to self-host font files so that I can organize them without Adobe guardrails, but that'll have to be a separate post.
