sorry, since we've switched focus as of a long time to Spriter 2, and will need to make Spriter 2 plug-ins and run-time code once Spriter 2 is done, we won't be making any new first party plug-ins for Spriter. At least no time in the foreseeable future.
Right, current Spriter and Spriter 2 have completely different data formats, features, and tech, so no current plug-ins will support Spriter 2 made files. New plug-ins will need to be made for Spriter 2 specifically.
