Three kinds of tags

There are 3 special kinds of tags

"Folder" tag, "Project" tag, and "Group" tag.

1. Folder Tag

Folder Tag serves to logically group related tags together. It's not really a folder in conventional sense because a tag may belong to multiple folders. You just take a tag and drag it to the folder. And then if you would like so you take a tag and drag it to another folder. The tag will be located in both folders.

You can remove it (by right-clicking) from the given folder as well. (One folder at a time).

For example, "Stanford" tag might be used in multiple contextes: it might be a "place", it might be a "project", it might be a "football team". You don't have to create 3 separate "Stanford" tags.

If you have more than one "place" marked by your tags, say, "DC", "SF", "Seattle", "LA", "San Diego", then you create a Folder named "place" and put all of the places, "Stanford" included - in there.

Then you have multiple Western Conference football teams and "Stanford" - one of them. In that case you create Folder "football teams" and place the same "Stanford" tag in there along with the rest of the teams. (Bears, etc.)

Of course, you can always simply use search field to find any tag. You don't have to group them in folders.

2. Project Tag

Project Tag serves to store all tags related to a given project, so you can find everything that belongs to that particular project later.

3. Group Tag

Group Tag serves to further classify set of notes.

Group tag might belong to any folder or project tag.

Example 1

25 notes all have the following tags on them: A, B, C

you may want to create fourth tag: D, place inside of it these 3 (A, B, C) and remove all A, B, C from the notes, so every note will have only one tag: D.

When you search for all notes with D - all 25 will appear.

When you search for all notes with tag A - tags with D will appear as well, because A is "part of" D.

Example 2

25 notes all have the following tags: A, B, C and need to be further subdivided into 2 groups: group 1 and group 2

So you create 2 Group tags: ABC1 and ABC2, placing A, B, C into each of them. (And remove individual tags A, B, and C from the notes)

Then you tag group 1 with the ABC1 tag and group 2 with the ABC2 tag.

Result: 25 notes divided into 2 groups, which you can see by searching for ABC1 and ABC2 accordingly.

But more than that, you still can see all 25 when you search individually for A, B, or C.

The last is important because any of the tags A, B, or C may belong to a project. If you simply replace all 3 (A, B, and C) with one new tag - you won't be able to find the notes when you searching for everything that belongs to a particular project. (let's say you will search for A, but A is gone from the particular note, you've replaced it with D - you won't be able to find it, unless D is a group tag).
