[PROBLEM] Disable Thumbnails

[doobster]

I just upgraded to 8.2.1 from 4.4 and a lot appears to have changed!  Thanks for all the work and enhancements.  But I'm hoping someone can direct me on how to disable all the thumbnails in the library "Browse by Folders" mode.  I'm seeing 4 different icons throughout my folders: artwork, "folder", "moOde", and "undefined".  What I'm looking for is an option to either turn them all off and show just the old "folder" icons, or show 2 (artwork and folder or moOde), but haven't found anything under preferences that'll let me do that.

My hardware is rather dated as well (Pi 2B and HifiBerry Dac+ Pro), but I'll go looking for newer hat options over in the Sound Quality and Audio Gear forums for advice on those.

Thanks!
