I never got on with the dualistic nature of the Factory/User structure with NI so I read here (thanks @D-One) that you can simply copy and paste all that's listed in the Factory Library to the Documents/Native Instruments/Maschine/Plugins location... and it works!
Pros:
1. unified search
2. no jumping between Factory and User all the time
Cons:
1. third party audio preview still work but NI products do not (solution?)
2. if there are updates to products, they will not happen.
Because of Con no.1, I'm thinking of a possible structure of using Factory Library exclusively for NI products and User Library for everything else.
What do you think?
