First of all, there is a File menu, which helps to organize input and output process.
Second I addad a Global Deformation script, that allows to make custom deformations over the mask.
The not-so big, probably because it's not finished yet, is the preview of Eye Editor. The system allows to create multiple layers each with some shapes, and mix them into eye texture. But right it won't be saved neither as parameters, nor as image.
