Since the product is open source thus you can modify/change the code according to your needs. If you want us to work on your needs, it will be subject to billing.
We wonder why you have given one-star review to "album order" and "date" points since what you are asking for are actually enhancements and not issues relating to the functioning of existing features.
Also, we enhance our product as and when required, and we have taken your feedback in a positive note. We'll check the feasibility to implement this feature in our product.
