The source link has the YAFLA - Yet Another Factorio Library Attempt source linked. It should be https://github.com/Wip-Sama/yaqsa
It would be nice to have some more feedback messages for command. Especially for retract_quickstart.
There also seem to be some bugs (single player). When you use edit_quickstart it doesn't seem to work. You are able to edit it but it will not save properly. It will just add to the loadout. The Clear Quickstart button also just adds whatever you set to the count. You start a fresh game and no_quickstart. You edit_quickstart and click Clear Quickstart, which will restore the default. You click it again and the counts double.
It's a nice mod! The interface is a lot more usable than other "starting inventory" mods.
