MC version 1.20.1

Hi, in what way it does nothing? Do the other aspects of the mod work? Do you have more hotbar slots than the value of max_slots_in_hotbar_row in the client config? Are the slots in a single row, or multiple, but with the wrong alignment?

the other aspects of the mod work, i'm currently only using the mod to limit the amount of shown hotbar slots to 3, and regardless of the value in the config these slots are always centred.

This happens even with no other mods added.

The alignment is set to Left here.

Ah, I see. The alignment really is more about how the additional rows are aligned relative to the bottom one, not how the entire thing is aligned, though I can see why that would be useful.
