suggestion:
add a way to display other items from other mods for example a crowbar from another weapon mod or so

possible solution:
a slot that does not limit to tool type (and maybe a option to change the tools position on the backpack)

Alternatives:
i did not come across any other alternative

It is possible, you have to make datapack and add item to acceptable_tools.json item tag

Yes

alright thanks
will that run on a server too ?

alright thanks
