Also, no concept of tags/labels? Are dependencies your primary means of organization?
But yes, dependencies are everything here. I use `tk dep tree` regularly to visualize the graph and click on the things I want details on. Typically I don't have too crazy of a list of open tickets so it's easy enough to find things by running `tk ready` and `tk blocked` and clicking what I'm looking for. For historical things, I just search in the `git log` pager.
If it'd be useful though, I can look at a `tk delete` command that deletes a given ticket and all of its dependencies to clean up a whole tree in one shot. Not sure I'd ever use it myself though.
