Hey @james that makes sense! We're working on a few ways to improve this.
The tags currently don't have a management page where you can edit/organize all of them at once. The intuition behind this was for tags to be a hidden layer that's surfaced through search or the graph, however there are some really good use cases for being able to manually organize the list and hierarchy of tags within a workspace; specially for making it easy to find things if you're starting right at the top (from the workspace).
So, we're going to start allowing nested tags, upto a depth of 2, and workspace admins will be able to organize workspace tags however they like. This will ship with the renewed workspace UI that will be coming out in the next couple weeks.
