Suggestions for a "tag management system"

Suggestions for a “tag management system”.

I would like to have a tag management system that provides more in-depth tagging functionality and can be managed visually like a mind map.

The current version of nested tags is very limited, especially when I want to change the tag hierarchy or content, I can’t even synchronize it to the global, which is very painful.

I hope this will be taken seriously by the Logseq team. Thanks!
