@agni, that's coming to Spriter at some point, along with several other features to alter the entire animation. Most likely after the pro features like variables and collision boxes though. @Yaomon17, glad you worked it out.
to everyone else, if you're using the latest version of c2, and not seeing the poses, please resave your project in the latest version of Spriter. It saves additional info that c2 uses for the pose feature.
Also, if you're not already aware, the selection wrapping feature (select all the pieces, and right-click - selection wrap) lets you scale and rotate the character as a whole in the editor. The plugin doesn't yet take the scaling into account, but that's coming soon.
