[Feature request] Allow users to favourite sounds in the library

[onethirdzero]

The order/sorting of sounds in a user's library seems to be static right now. It would be nice to be able to favourite/bookmark a sound so it's easier to locate, instead of having to scan all the names each time.

For example, my current favourites are Coffee shop and Light rain, but it's a bit jarring to have to select them among other sounds in my library that I don't use often.

The favourite/bookmark could be something as simple as having a "Favourite" icon on the sound's card or have the sound show up in a separate row from all other sounds in the library.
