In the tags:/ view one can see all files associated with a certain tag. (First observation: When I hit Del to delete a tag it is not obvious if only the tag will be deleted or all files associated with it) It would be nice if it was possible to see the full path of those files listed under a tag.
Does adding the "Path" column help?
That does help, but it's pretty awkward to have to do this every time you want to see a file's path. See also Bug 340393.
Tried adding both the "Path" and the "Link Destination" columns when looking at a "Tags" folder. Neither are populated (as per Neon Testing, Plasma 5.18.4, Framework 5.70.0) There is an overlap here with Bug 418590
