Do you mean this one? It looks like a handy 
tool for funscripts, I’ll have a look at it.

I have all my funscripts in one directory structure with subdirectories for site and author from which the scripts are symlinked into the video folders with the correct name for Stash.
So for bulk fixing my script is probably a bit easier, but for fixing individual scripts with more granular control HandyControl definitely seems like the right tool.
Thanks for mentioning it, I hadn’t found it myself yet.
