I haven’t found this exact item in the history - maybe I’ve got this wrong, I believe tags are created and managed at the database level for items contained in a given database. If you maintain multiple databases containing perhaps similar subject matter, you must re-create many of the same tags in each database.
An option to point all (or selected) databases to one global tag list would be great.
Why is this actually necessary? E.g. moving items from one database to another or tagging an item automatically creates the tags if necessary.
And autocompletion of tags of items in the global inbox uses the tags of all databases already, therefore one option would be to tag the items before moving them to the destination database.
