Book-Based User Interface

This idea has already been partially adopted in UO as part of the Mondaine's Legacy expansion, but the current form is only a partial implementation, and not very immersive or complete.

Essentilally, I would like to see most of the multi-use skills (crafting, magic systems, etc) implement a book-based user interface. In this model, each of the multi-use skills would be represented by a book, and as additional portions of the skill were learned additional pages would get added to the book. On the surface, this model would operate in much the same way that spells are added to a spellbook as they are learned, although there are many additional ramifications if the system were implemented in a wholistic manner.

Some of the design elements that I would like to see in such a model:

As can be seen, there is a tremendous amount of potential in the book-based metaphor, which goes well beyond the capabilities of the current game system. And while not all of the suggestions are practical, there is plenty of room to implement much of the system within the current model, which would make the overall gameplay more immersive and enjoyable.
