1 The crafting on a Workbench is annoying as Hell i rather click one time how many i want to make instead of holding a button for about 10 min...
2 The Item System aka Weapons fruits and other stuff you can equip should be fast accessable if you need to fight and got either nothing in your hand or something that does no dmg it is nearly impossible to switch fast to your weapon!
Something like the building menu would be nice!(1,2,3 and so on)
3 In the Crafting menu it would make it faster if the name of the item is directly shown if you got it or not!
