@mark, yes it should not be limited to gradients but there are workarounds:
Global colors, gradients, brushes and pattern swatches are not supported in CC libraries.
But as a workaround you can drag an object using a brush/pattern/gradient/global color to the CC Library
You can also drag multiple items using different brushes/patterns/gradients/global colors together into a CC library to simulate a library.
The easiest way to add them to a new document is to hold down the Alt key when you drag them from the library and place them in a new document. The patterns/gradients/global colors automatically get added to your swatches panel.
You can hit escape before you click to place the object(s) or delete the dragged library items because the swatches and brushes are now part of the document.

This idea should include *all* swatches, pattern fills, and should also be able to save brushes to libraries.

please make this happen. And while you are at it, make a Senai AI extension that can create illustrator / Photoshop gradients from bitmaps.

Please make this happen. If it can exist in a 'local library' like Swatches/Symbols/etc. it should be able to exist in a shared Library too.

Also, fill patterns, please.

now is 2021, still can't add gradient to CC library.... frustrated

Please let us create gradients in adobe color and apply them in indesign and illustrator

Can't believe we still can't save gradients to CC Libraries after the massive gradient revival over the past couple of years. So frustrating to have to make my gradients over and over and over again

I don't think Illustrator is being developed anymore. Seems like one person at a remote office somewhere is doing the 'updates'.

Meanwhile - been using Adobe XD and it's the AI we always wanted.... just doesn't have everything. But has a surprising amount (just well-hidden for a cleaner UI experience.)

Incredibly disappointing that this issue is still under review. Such a no-brainer of a feature.

Here's betting that this gets added within the next 10 updates with no announcement, and no special note in the update log.

Then this thread get deleted without getting addressed by an actual employee. Just the way Adobe rolls I guess.

It is Insane! that this is still under review.

Really? Under review since 2017?
It will end up being the most researched and therefore best implemented feature yet. ;-)
I can hardly wait. ;-)

Bump +1000:)) Needed so badly!

I would really love this feature! I do a lot of work across InDesign & Illustrator and use CC Libraries to streamline.... would be great to be able to add gradients!!!

Yes, this is so dated. Adobe, please move this function forward in your next update already. Instead of tweaking other tools to make it more basic and lessen efficiency. PLEASE create this for efficiency. Thank you.

It's ridiculous that this hasn't already been implemented. Either make sure all Creative Cloud applications have the same gradient customization tools or allow gradient swatches to be added to the CC library so you can share them across applications.

私も賛成です。是非お願いします。グラデーションには円形や線形のようなタイプと、角度の設定もありますね。これも記憶して、その通りに適用するか、グラデーションの配色だけを活用するかを選べると便利です。

Upvote for gradients to be added to the CC library. If you add an object with a gradient to the library, you can't use it as a swatch either.

C'mon Adobe!
Indesign gradient system is awful, do something at least about cc library!

For me, would be great to save gradients to the custom swatches i made!
