Most modern design applications that export to the web, mobile, desktop, tablet, and screen/UI design in general include this particular GUI: a plus/minus to add or remove export options per selected object or group of objects (or the entire screen) with standard naming practices (still editable though).
The ... menu option could open the existing save for web option in PhotoLine to fine-tune the settings for each export. A very nice combination of the old with the new

This would modernize PhotoLine's screen design export options in one blow!
