Version 1.5 is out. New are two major features: Vibrance adjustment (like saturation but slower and looks way better) and a much faster Blur. Those two form the foundation for the other additions: a Tilt Shift effect, a Lomo filter and a Velvia filter.
Version 1.6 is currently in the beginning design and development stages. This version will include an entire remake of the UI. The time has come, as the lists of effects have become long and there is still more I would like to include.
