Karellen, thank you for your help and your patience. I was finally able to install the rmrector repo and then the Artwork Beef add-on. My problem was a misunderstanding of how to install a repo from a zip file (Kodi newbie). I finally understand you need to manually download the zip file to Shield storage or the host file system (an SMB share in my case) before you can "Install from zip file". Once I did that, the install went as described. I was trying to add the url to the zip file as a source in File Manager, thinking that would allow me to install the repo. That methid wasn't working.

I have since found a YouTube video that discusses Artwork Beef configuration options, so I'm moving on. Thank you again.
