I would like to see the ability to create a custom parts library, with a dashboard interface that allows me to categorize parts into folders. For me, this might be electronic components I need to account for- connectors, headers, batteries, displays, etc. These are mostly not available from generic CAD model sources. I either build them or get them direct from the manufacturer. It's best if I can identify them by manufacturer's part #, but this isn't conducive to searching and placing given the current interface. But most of us have parts we need to reuse over and over. The current interface makes these very difficult to find.
This is related to an idea- or several- around file organization, for instance http://forums.autodesk.com/t5/Request-a-Feature-Fusion-360/My-2-dashboard-cents-eat-it-or-not/idi-p/... These should ideally be under one umbrella. Really need a way to link closely related ideas.
