RE: The wretched gradients are currently not tolerated inside swatch folders …
Why can I not drag my gradients into the Libraries Panel. When is this going to change? Very basic necessity to organizing assets and colors inside the Libraries panel.
[Branched: this question is about libraries, not swatch groups]
But as a workaround, create obects and fill them with gradients and patterns.
Drag (add) those objects to a CC library.
When you want to use them in another document, Alt drag them from your library to place them embedded.
that doesnt work when creating a graphic in photoshop and taking it into indesign and vice versa
No, it works for Illustrator files.
Gradient exchange between applications (and especially between Photoshop and other apps) are almost impossible.
