Design library of UI elements. What is the best way to organize?

Question

User interface

Hello,
tell me what tools and approaches you can advise / not advise for organizing, storing, using and developing project interface elements.
In our game project, a large number of typical interface elements have accumulated, which are systematically reused and changed. The question arose about the organization of the library of elements. Now we are looking for the right approach and tool. Of the tools, a colleague offers Adobe Creative Cloud. We would be grateful for your advice, experience, recommendations, links.

Answer 1

Mail.ru was advised to keep the layout in Dropbox. I would do the same, works well.
Craft, Brand.ai and other competitors seem to be better than Adobe Creative Cloud, but still inconvenient.
