I've heard a lot that there's no point buying a toolbox for more than a bigger bag when the toolbox doesn't do anything the bag doesn't. Just like spices automatically go into the spice rack when made, picked up, or bought, and compounds go into an alchemistry kit, tools should go into a toolbox by default. This has been brought up before in the ideas section, but since I couldn't find anything more recent than 10 months ago I made a new thread. One reply mentioned putting the toolbox in the first slot of inventory, but I like to reserve that slot for miscellaneous items to be sorted later or stored, and the other specialized bags don't require being in the first slot.
