The hardened inserter, name w93-hardened-inserter is currently on the logistics tab, it should be with the rest of the inserters in the Bob's Logistics tab. There is already code to handle the w93-hardened-inserter in this mod code however it is gated behind the scattergun turret mod being loaded rather than the scattergun turret mod and the modular turrets mod (same author perhaps?).

In addition, all the modular turrets 'turrets' should probably go on the "Fortifications" tab with the rest of the bob's and vanilla's turrets rather than on the Weaponry tab that it is currently on (especially with how otherwise fairly empty the Fortifications tab is and how extremely full the Weaponry tab is by scrolling for over 2 full pages worth).

IIRC the modular turrets mod is internally called scattergun mod.

I don't use the fortifications tab. I find it hard to categorize things in it. Some things really belong into both.
