With the advent of Mavericks, files don't have only labels, they have tags. You can still use it just like labels (and have the classical 'work', 'home', 'urgent', 'to file', ... tags), but it is more powerful than that.
The difference with tags is that you can have multiple tags for one file (while there was one or none label). My question is two-fold:
- How many combinations are there?
Is there a better way to organize tags than the categories:
- Combination to produce many labels: 'red - blue = work, projectA' ?
- A hierarchical way?
Find relevant, relatively independent axis:
'blue = related to work',
'red = to treat urgently',
'violet = general interest',
'green = recycle'?
