Hi!
Maybe it's an idea to add a ring and/or glovesfor when you're smithing.
Like when you have to smith an x amount of rune bars or something else , you have to use a lot of coal so it will be taking a lot of time to make them.
And with this ring and or gloves it will save you space in your inv for the rune ores so you have full inv of runebars or another ore/bar.
