Spriter is now at version 0.8 and has all major features working.
I'm paying programmers to make Spriter plug-ins for several of the major game authoring packages including Construct 1.x(The Construct 1.x plug in will be free for all Construct users)so that users of those packages can benefit from all of Spriter's intuitive and optimized features.
Aside form general tweaks and improvements, one of the most important feature additions is the ability to export finished animations as sequential images.
I've now split Spriter into two versions: Spriter Lite (free) and Spriter Pro.
Spriter Lite maintains most of the features you're already used (with tweaks and improvements) But Spriter Pro has the full set of features necessary for art asset production for a major game title, such as the ability to merge Spriter projects, Scale entire Spriter projects, and export sequential 24 bit PNG images with alpha channels intact. (Spriter lite can export sequential images, but only BMP without alpha channels.)
Spriter now also has a Facebook page at: http://www.facebook.com/pages/Spriter/206503089402447
Please help support Spriter by spreading the word about it.
If Spriter is useful to you and you want to see it succeed and improve as rapidly as possible, please consider taking advantage of the Early Adopter sale to get Spriter Pro for a drastically reduced price. Those that do will be greatly appreciated and their bug reports and feature suggestions will be an important part in Spriter's development.
Thank you very much,
