Was this your reasoning with the restore command. In the event you delete a working file from your current directory then just:

$ touch fileName.ext
$ kak fileName.ext

:kowsky-restore

Where back and good to go? Thats how I read you post, did I get it to plan or am ‘I out there Jerry and loving every minute of it’.

Nice job on the additional ls command and kak-back.py refactor.

Cool, yeah command line makes more sense for restoration. I had a thought when I viewed your ls command, a glob or regex on a file extension would be nice as to remove the clutter.

Talk later, bye :wave:

Exactly what you said - except you don’t even need the ‘touch’ part.

Truth is, I often use the restoration feature from the command line and not from kakoune
