On p. 15 of the latest manual (DT 3.0.1) it states (emphasis added):
“In the case of multiple selected items, any tags common to all the items will be shown in the Info inspector and Info popup. Tags unique to specific files aren’t displayed.”
This does not match the behavior I am seeing. In the screenshot below, the four selected files all have the tag “NERGC”, which does not appear in the Inspector or the tag bar (or in the info popover, not displayed here). This is apparently because they also have date (year) tags that are different; the first two are tagged “2015”, the third “2017”, and the fourth “2019”.
If I select only the first two, which have both “NERGC” and “2015” tags in common, then both tags are displayed in both the Inspector and the tag bar (next screenshot).
I should note that on p. 32 it states (emphasis added):
“The tag bar is also visible for multiple selected documents when all the documents have the same tags attached. Use it to change the tags on multiple documents.”
Apparently this is the expected behavior for the tag bar – that all of the tags must be the same for all the documents for them to appear in the tag bar – and the Inspector and info popover are behaving the same way, despite the statement on p. 15.
I believe you should be able to select multiple files and be able to see what tags they have in common, regardless of what other tags they may have. This would allow you to remove a tag from all the items (by simply selecting and deleting it in the tag bar) or quickly check whether a group of files is already tagged uniformly with a particular tag.
I hope you will fix this so that the tags in the Inspector and Info popover work as stated on p. 15, and make the tag bar behavior consistent with the other features.
