Tag groups are a limited hierarchical structure that assist in de-cluttering the massive amount of tags that can emerge in a SuperTag collection. By default, tag groups end with a “+” symbol, but you can customize this in your settings.
The basic idea is that a tag can be part of zero or more tag groups, and that wherever a tag would be displayed, it’s tag group is displayed instead. In effect, the tags are “grouped” to lower the number if displayed tags. An example will make this more clear.
Consider the following example. Suppose you had a
movies collection, and some of the tags you created are the lead
actors for those movies. You might have tags like the following:
al_pacino/ clint_eastwood/ daniel_day_lewis/ jack_nicholson/ mel_gibson/ morgan_freeman/ robert_de_niro/ tom_hanks/
You also decide to tag your movies by director. So you might have these tags:
christopher_nolan/ david_lynch/ james_cameron/ martin_scorsese/ quentin_tarantino/ stanley_kubrick/ steven_spielberg/ wes_anderson/
Without tag groups, all of these tags (actors and directors) would be thrown together:
al_pacino/ christopher_nolan/ clint_eastwood/ daniel_day_lewis/ david_lynch/ jack_nicholson/ james_cameron/ martin_scorsese/ mel_gibson/ morgan_freeman/ quentin_tarantino/ robert_de_niro/ stanley_kubrick/ steven_spielberg/ tom_hanks/ wes_anderson/
If you wished to filter by director, without having a specific director in mind, this can be challenging. What you really want to see is something like this:
With each of those folders containing the corresponding people. Tag groups allow you to do just this. By assigning
all of the actors to the
actors+/ tag group, and all of the directors to the
directors+/ tag group, anywhere an
actor tag is displayed will be substituted by the
actors+/ tag group, and same with directors.
In a way, it imposes a very limited 1-level hierarchy on tags, so that they can be more logically grouped together.
To create a tag group, simply make a directory but suffix the name with “+”. Now you can symlink other tags into it.
