Feedback wanted for my android app

To clarify I'm not the developer of this app, I am simply the publisher and content provider.

I have an app on Google play with 2,887 downloads and 605 active users (not a great deal but a huge amount for me). I'm looking for ways to improve the apps homepage and user interface. While I'm not the developer (As i stated above) i did help to design this app a bit.

My vision is a complicated one because it wouldn't be easy to implement, but it would also cause a little bit of a headache from my point of view as content provider (too technical to explain). While it looks pretty it just wouldn't work.
