httm is interactive, file-level Time Machine-like tool for ZFS/btrfs/nilfs2 (and even actual Time Machine backups!).
It would be nice to get some httm goodness for working with restic snapshots as well.
I have opened a feature request for the support of httm on restic mounts. As I am certainly not the right spokesperson for restic, perhaps someone more qualified could join the discussion on httm on mounted restic repository?
