Fiddling is a convenient new way to experiment with potential combinations and recipes. In the dark old days before fiddling, doing so required three clicks, whereas now with fiddling, the same task takes only a single click. For those of you taking notes, that's a threefold increase in productivity! Actually that's slightly hyperbolic (but only slightly!), nevertheless I think you'll still appreciate the new fiddling interface.
For those of you too busy to read the previous paragraph, try the new [ fiddle ] buttons in your Inventory and I think you'll be pleasantly surprised.
In other news, about a week ago the Wise Sage deemed it useful to start noting the best lemming impersonators as well as the most violent players, but he forgot to tell anyone until now.
