Import tags from StashDB? How to set the right tags with the right StashDB ID?

Nice, so tags are matched by name.

Unfortunately I did not find any active plugins to sync all tags in the plugin list within Stash. However inspired by your hint I now installed Tag Manager , which does a lot of heavy lifting and is easy enough to add as a new plugin repository.
I hope in the future external repositories are more integrated without the need to search for them outside stash first.
