Would be nice to have a mundane crafting system.
I've heard rumors (two years ago) that it is already implemented but simply isn't available. Not sure if that's true.
Two years ago I tried submitting a simple prototype based on D&D crafting system, but it didn't go anywhere.
The prototype is available here:

Talk to the blacksmith to get crafting bag and materials.
To craft, activate the bag from your inventory via rightclick menu.
When receiving "the area is unsafe" message, kill all enemies in the area.
One session (one rightclick) represents one day's worth of work.
Oh, and DON'T try to craft heavy armor straight away - it'll take eternity.
