I also agree with @ImDaveM about the functionality of the libraries and the complexities necessary to create components.
When I switched to Fusion Electronics a little over a year, I was new to Eagle and coming from the Altium world, I immediately didn't like the workflow and decided to switch to Fusion Electronics. I probably spent two weeks trying to understand the libraries, the library structure, how to make components, where which libraries were, how to make sure I didn't screw anything up. It is very confusing.
I'm mean, come on - Fusion Hub Libraries (Fusion Electronics - Cloud), Libraryio libraries (Legacy Eagle Libraries - Cloud), Local Libraries (Hard Drive)
Definitely need a more robust search engine for going through all of these libraries and a better way to represent the results of the searches. Possibly, a graphic of the Component/Footprint with the description and all user attributes listed.
The Fusion Electronics developers should really take a look at how Altium does component attributes. You are able to pull all the information (PN, MFG PN, Part type, size, etc) straight from sources like Digkey/Mouser, even has an option to have the datasheet attached with a link. All this is done in 1 or 2 clicks of the mouse.
There are so many intricacies that this post could go on and on, but I won't.
I understand that Fusion Electronics is a work in progress, but some of the features being prioritized seem out of order to me.
I think it will be a very long while before Fusion Electronics catches up to the current functionalities of other electronics design EDA tools. Just my two cents, spend it wisely.
Here is a forum post that gets into the details of understanding the library structure. There are documents attached to some of the posts. If you are interested.
