From the developer:
SpriteSheet Preview is a simple tool that enables you to preview created sprite sheets. Just drag and drop your sprite sheet, configure the rows and columns and preview your sprite sheet before your assets go to the game. You can play/pause/loop your animation, control the FPS of your animation and configure the animation interval to preview a specific animation inside a sprite map.
