you can save a change to the launcher and then look to see which files recently changed… then back up the file that captured the change.
from my notes
#to find the last 10 recently changed files from a config change or fat fingered file save
find -type f -printf '%T@ %p\n' | sort -n | tail -10
i find it handy to make an alias for this in my profile so it’s always handy.
