Customize your items' stack sizes based on their internal types and names dynamically and easily.
In other words, you can set ALL modded and vanilla inserters' stack size to 100 with one line and don't need to change it for every single inserter in your mods.
There are functions to write locale and settings but I'll leave it there until the mod is considered finished.

If any, contact me through THIS mod's discussion board; I would check it every now and then.
