I'm building a library with over 2000 assets in it (9 color versions of over 100 icons, etc.). Because I have to drag graphics in 1 at a time, it is taking forever to create the library. CC Libraries really needs a way to batch import files, and a way to create a naming syntax to more quickly rename assets.

Alternatively, you could allow us to add color settings to assets, so that you can select the colors for different parts of a graphic from a set of brand colors (ex. a green circle with a white icon) when dragging asset(s) on to your artboard, so you only really need 1 version of each asset in the library.

I've seriously spent over 20 hours on this library and I'm not even done yet, between how slow the library is to add and load assets, and all the bugs I've encountered along the way.
