Hello!

Not sure if you guys take mod suggestions, but there are some mods that I have added to my personal pack that I believe might be a great fit for the default mod collection.

Shrink: https://www.curseforge.com/minecraft/mc-mods/shrink_
Absolutely amazing for getting between cables and pipes and routing them well. I made a recipe for it around MV, think it fits nice there.

Measurements: https://www.curseforge.com/minecraft/mc-mods/measurements
Self explanatory, great for planning out areas for new processing setups and cabling long distances.

Carry On: https://www.curseforge.com/minecraft/mc-mods/carry-on
Absolutely phenomenal for moving GregTech machines without wiping out its settings. I haven't had any issues using this with the machines, and I honestly probably could never play another GregTech modpack without it.

Affinity Enchantment [FORGE]: https://www.curseforge.com/minecraft/mc-mods/affinity-enchantment-forge
I absolutely hate the mining penalty for flying in the air, and this rectifies it!

Redstone Pen: https://www.curseforge.com/minecraft/mc-mods/redstone-pen
This one might be too far from QOL, but it's probably the most robust "basic" redstone expanding mod that doesn't detract from GregTech or add anything unnecessary. It combines well with machine control covers on multiblocks when the redstone power source is too far from the machine face.

Notes: https://www.curseforge.com/minecraft/mc-mods/notes
Adds a page with a keybind where you can write notes and pin them to the screen. Useful for making personal checklists and planning.

Calc: https://www.curseforge.com/minecraft/mc-mods/calcmod
Basic calculator functions all from ingame chat! Has some other functionality that helps with vanila setups, but I mainly use it for quickly calculating numbers ingame without needing to alt tab for the calculator app.

Sorry for the massive wall of text haha, but I really wanted to highlight these mods as they've been an absolute delight to use in the modpack, and I thought maybe others would enjoy using them too! Let me know if this sort of issue request is unnecessary, and I'll refrain from making more in the future.

Thanks!
