Please consider putting a note on skills/actions/etc. like "Talis Fast Throw" that state that it is a stance and must be toggled in the sub-palette to utilize. Some people may not want to get the skill/etc. if they know this, and not putting this in may cause them to regret the decision, requiring them to refund points/etc.
In addition, make it clear on the description that the stance stays active even if you switch sub-palettes.
