Thanks for the great suggestion. We will look into the implementation. As you've mentioned the randomiser shouldn't be completely random because this would create a lot of 'useless' thing views. So the randomiser should be based on some kind of like or view count, this makes it technically more challenging. But we will definitely take a look at it soon.
We are planning on releasing a new version of the app on Monday. After that the roadmap is clear for some investigation!
