One of the actions I perform quite often is switching between crafting menus and hearthling character info pages. Usually I do this to check on experience progression, mood or previous jobs. Currently the only way to do that is to find the hearthling via town population menu. And while the menu itself is convenient, it still requires additional time so switch to it and find him.
What I suggest is to make some kind of a link (button or similar) to quickly switch between crafting window and hearthling info window.
What makes it slightly more complex is that a hearthling can have only one active profession (DB relation one => one), but for a single crafting menu there can be several crafter hearthlings (DB relation one => many).
