Technically, I think you can use a Style in a Smart Bone Action, at least for the main Style Panel properties. The problem is that you can't see the keyframes on the timeline when using a custom Style so it becomes really awkward to edit.
You can, however, see a regular Style's keyframes , so the workaround for custom Styles is to copy the hidden keys using the Style Panel's Copy button, pasting them into a regular style, editing the keys there, and then copying and pasting them back into the custom Style. (Way too much trouble, IMO, but if you really need to do this...)
Anyway, yeah, I hope the Style values gets opened up too.
@Guyver93, I'm not sure why the keys are delayed in appearing. That does seem odd. I'll take a closer look at the video at lunch.
