One of the most frustrating things is that I want all of my tools in the same place so I don't have to open 5 bags just to make one recipe. Currently I'm holding off on purchasing bags so that I can keep as many tools in the main bar as possible. I think a nice solution would be to have a "Toolbox" akin to the element bag/spice rack. The toolbox remains open at all times so you can access all of your tools while creating stuff but can only hold tools. Available slots would be up to your discretion - though forcing us to purchase two toolboxes that we have to switch between seems counterintuitive. If you decide to go the route of a smaller toolbox - maybe have the option of purchasing an "Extra Large" tool box that takes up two main bar locations for the sake of one very large always open listing of tools.
