Finally, with 2.6 we'll introduce settings per project and view, so stay tuned for that and let me know in case you have any further questions.
Our users are hoping that these 'saved settings per view' are going to include sun angle, rotation and brigthness. For us, the goal to save settings per view is to be able to reproduce the same shot again in a reliable manner. So we can generate the same shots over and over again while the design changes.
It's only going to be partially useful without the sun angle, rotation and brightness.
