Yeh I came here to post this. I preferred this approach as user permissions are a bit easier to consistently verify as a second layer of defence.
I also found the author to be helpful and responsive and the tool to be nicely minimalistic rather than the usual vibe coded ever expanding mess.
‘brew install sandvault’ and running ‘sv’ should get you going.
(full disclosure: I created the Homebrew formula and submitted a few PRs to the project)
Means a lot coming from you - thanks for taking the time to post, and for taking the time to make the Homebrew formula. (I am also a fan of the author's (webcoyote's) other work.)
