Sometime I need to save guides positions, so every time I load .psd file I need to position guides back. I think if some new features (like 3d figures that already in 'to do' list) will planning to implement, own format would be really useful.
Is there a plan to do own file format for Paintstorm?

We don' want to create an own format - this creates additional confusion, but maybe we'll do it someday if it will be a very necessity. But I think we could add some custom parameters to the PSD file, in this case, it could be lost after photoshop resaving... I'm not ready to ask this question right now It' should be tested.
