Spell book reorganization

[Cagus]

Hi,
I have seen many good gadgets made here on arelith, and wonder if there is possible to do something about rearranging spellbook.

I just started cleric, and I have to say, it is mess. The spells are not in any order, not alphabetical or other.
Same goes for wizards, where useful spells changes with levels.

So I propose to make system to change spell position in spellbook, so those one uses most can be found easily (one can put them as first) and those which one has no use for can be at the end of list.
