I'm in the process of switching from the old Evernote Legacy app to the new Evernote Desktop app.
There are a few missing features that I loved in the old app.
This is one of them.
Copy tags from one note to another (Assign tags)
In the old evernote legacy app, the "Assign tags" function (Ctrl-Alt-T) made it very easy:
to see the tags of multiple selected notes
and to copy the tags from one not to another or to a bunch of other notes
In the new Evernote Desktop app a similar function exists (same shortcut Ctrl-Alt-T), but it shows all existing tags, not only the ones that are relevant to the selected notes.
This makes it very difficult to do what I used to do in the old legacy app very often:
select two or more notes
make sure they all have the same tags
