Managing "MyAssets"

Thanks to the Lunar New Year Mega Bundle and bundles before that my asset library is evolving a lot and I'm very happy about that. But it also brings a luxury problem as I lose knowledge about all the stuff I could use. But always importing complete packages to projects blows up the size of them too much.

Therefore I'd like to ask, what are your ways to deal with that situation? My first idea was having a simple project with all downloaded assets to lookup asset packages and only import the wanted parts to the current project.
