TL;DR
Make default inventory width of 10 items per row changeable in menu, or add "inventory_width" value to data.raw["player"]["player"].What ?
Add an option to the menu, maybe under graphics, that sets the row width of player inventory.Why ?
Normally, in factorio, you wouldn't need to scroll through your inventory.But when you use a modpack made up of other modpacks, you do.
Especially when your inventory grows beyond 350 slots, which yes, is possible...
ANYHOW, I happen to play Factorio on a rather obscenely large (30"), WIDE monitor.
Result: GUI looks really thin, as inventory width is stationary ATM, relative to game height.
