Is there a way to identify the resources in your library that are untagged? With L7 this was a snap. Not so, at least for me with L8.
Sort by tag - those without tags sort to the top.
selected Tags->Mytags I could not see the ESV. Help!
Sort on - no filters just click on the heading line for mytags and it will sort on that column.
I think what MJ is suggesting is that if you sort the Library by MyTags, then you can see those without tags from the facet on the left
