[@Peter Blaise] Hi Peter, thank you for your feedback, this is very important to us!
In fact, there is a batch processing option. Check out this short video lesson: http://home-photo-studio.com/actions-batch.php
Hope you’ll find it helpful.
The software doesn’t overwrite originals unless it is specified in the settings. But the default setting is to suggest that the user saves file as… and creates a copy with a new name. Just to be on the safe side, check what you have under Edit > Settings.
As for the other features you mention, I’ll forward this to the project manager and we can hopefully add these in future updates.
