During my time using Storyline, Articulate implemented a superb new feature to the software – the Media Library. I'd suggest you watch the introductory video here. I was incredibly impressed with what they had done when the library first came out. The ability to see all your assets in one location, to easily swap or amend images (without having to visit slides) was superb…and the team asset library features make it even more powerful. But they weren't done!
