Used Set Update Channel to Beta after a 'standard' installation with Auto Download Updates = No, restarted Logos, and was presented with the Download Logos 8 Library window. I chose Recommended.
When complete, All resources is the same as v8.2 - so no more Hidden resources!
The only problem is a download notification for 10.75 GB (the remainder of my resources).
There is an option to Cancel Download for resources "Not on this device", but it doesn't work, even after a restart. Info shows the resources as "Downloading".
