After a long while of SNS v2 simply not going anywhere, I rewrote it in a cleaner, more concise, and more focused form. As far as I’ve tested, everything in SNS v2a seems to work, though I’ll be working toward expanding its functionality again.
Specifically, for SNS v2b, I’ll replace explicit calls to vim with calls to the environment’s $EDITOR, and implement a special vim-only mode that will (finally) allow for in-place editing of encrypted files.
