Library panel in Illustrator is no longer as convenient
It appears the Library panel is now more simplified (version 26.3.1), and users can't specify colors or fonts. The assets are only imported as "text" (which includes the entire copy), and "Artwork." I don't see any options in the Library menu to make these specifications, and all of the icons along the bottom of the panel are gone. Please allow users to add fonts and colors (independently of objects) again. Without this option, Libraries will not be as useful as they once were.

Here's a novel concept for you. How about if you made it so the "Libraries" panel ACTUALLY WORKED??? It'd be super cool if I could use the Libraries panel without having to restart Illustrator every time I open a new document. Call me crazy, but this is definitely a feature I would like to see.
