Recovery of unsaved files after crash. #528

Hello,
Silly me didn't ctrl+S, and my laptop froze without me being able to avoid forcing the shutdown.
I'm not holding to much hopes, but is there any way to recover unsaved progress upon restart ? Or is it irremediably wiped on shutdown ?
Operating System : Archlinux
Due to the current problem with electron, I cloned the repository and built inky on my machine directly.
Thanks in advance for the help !
