First let me say BEAUTIFUL mod, I absolutely love using it!

So, my only request thus far is some type of either ModID / InvTweaks style sorting like AE2 had, where it sorted almost identically to how JEI sorts things. Any possibility of that happening?

Unfortunately I won't be able to implement this as JEI sorting depends on item register order, and RS has no such concept.

You can use @ to filter on mod id?

And great to hear you like the mod!

Right, I know you can filter by ModID, but I was wondering if you could add a sort by ModID for Grids, which starts by displaying everything from Minecraft, then sorts everything else by ModID Alphabetically, similar to how JEI sorts its items in the Item Lists.

Sure, i'll try to get this in for the next version
