More tag types / category types

Use case or problem

I’d like to be able to assign different tag types to help categorize information/notes further. For example:

Main tag: #webdevelopment
Subtag: !learning

Main tag: #webdevelopment
Subtag: !error

I’d like to assign other values to notes such as:
!event !alert !info !information !learning or any custom kind of tag. That way I can filter through these tags in the file explorer.

The point of this is to help sub-categorize information further to make finding and filtering through lots of notes even easier.

Proposed solution

Add a different tag type. Whether it be double ## or !.

Either add it as a separate plugin, or add onto the core tags plugin.

Current workaround (optional)

Searching for and adding as: #!subtagname even though it isn’t as distinct.

Related feature requests (optional)

Possibly another categorization feature. Though with tagging and folders this might be unnecessary.

My whole goal of using obsidian is to categorize and commit all my notes daily. I then like sorting through them all chronologically by different tags and other values.

Thanks again for the great app!

This is already possible with hierarchical tags try #webdevelopment/learning
