I didn't like how the default Combat Ability Window displayed the disciplines and skills truncated so I made this mod to fit my tastes.
The "S" button will be hidden when a discipline is running. Clicking the discipline icon will cancel the current discipline and the "S" button will display again under it.
The skills and disciplines are listed vertically with wide widths so their names are not truncated. This feels a bit more like the spell icons that spell users have and I feel more comfortable with this setup.
