I really miss the possibility to create a tree structure for tags.
I mean that the tag B should be created as being “under” tag A.
What are the use cases?
I’ll try to provide some convincing examples.
Tagging photos. I like to have information about who is in my photos, the location and often other things. Some parts of this information is in the folder structure, yet the number of tags is beginning to be hight. With a tree structure I would have two advanteges:
less confusing tag menu: I could go to the tag menu and select from a structured list a tag (e.g: places -> Berlin -> office; or People -> colleagues -> John) instead than from a huge list with an alphabetical order (the alphabetical order is not the order I mentally use in this context)
tags labels easier: I find way easier to define e.g. people tags if I have a “structure”. can know several persons with the same name, yet I find “ugly” and counter-intuitive tags as “John the colleague” and “John the cousin” and “John the friend”. I would really prefer: “People -> work -> John”, “People -> family -> John” and “People -> friends -> John”
Business trip: suppose you have a business trip in which you have some meetings with clients and a conference. Different tag trees could help you to organize the related files. I would use for example:
“trip X” -> “Day 1” for a quick and dirty access to all the things of that day. Under this you could find the tickets, hotel reservation, the files for the meeting at day 1 (contracts, brochures, whatever…)
“Conferences” -> “Conference Y 2016” and also “Clients” -> “Client Z” -> “contract W” for a more structured access to my presentation and business files
“Subject” -> “subject whatever” to an access to the presentation when the office is looking for something related to the subject of the presentation
I know that you can use the hierarchical structure of the folders, yet I think that it is not enough and usually I have two or three different hierarchies, like in this case
Give different access to global tags by user feature: tags with a Hierarchical structure would make much more easy to manage access to different tags: the admin could manage different “branches”, not a huge quantity of single tags
