Ixobelle on crafting

Ixobelle, previously from NotAddicted, has an own blog now, with an interesting article on crafting interfaces. The principal question is whether crafting in its current form is too easy, just click a button with the ingredients in your inventory. I don't know if Ixobelle's crafting interfaces are the best solution, but I sure would like to see more crafting systems like in Puzzle Pirates or A Tale in the Desert, where you actually need some skill to craft something, and the better your skill, the better the item you craft.
