skill window

[Aequi]

As far as i could see in the "can't be done" list, the skill window doesn't seem to be mentioned.

Would it be possible to mod the skill window so related skills are listed next to each other?
Like all the tradeskill-skill's in a group.
Havesting skills in a group.
Combat skills.
Spell skills.
Skills that determine what equipment you can use.

Sorting things in Alfa or skill size doesn't seem enough.
