I'd switch the position of the custom crafting groups (alkaline earth metals, post-transition metals, etc) to after the default ones, instead of before. I personally have muscle memory of trying to craft inserters, belts, etc in the first tab and having the AEM group be there really messes with me.

Hey! and yeah, i have had this requested before (and honestly, has gotten me aswell a couple times) - i do plan to change it as soon as i can (going to try and fix it today), but i need to figure out why i cant get them to move, before i can get them to move 😭

just gotta set the order for the item-group to be after the base game ones, which are in base/prototypes/item-groups.lua

i did try that at about 0.4.6, but for some reason it just did nothing, i will try it right now though as im currently working on some new elements :]

figured it out, be put into the next update which'll be in about.. 10 minutes?
