MyHeatpump: Day view isn't clear what date it is

If you're using the day view, then scroll left/right a few days... It can get very easy to get lost as to what day you're looking at

Displaying the date somewhere on the screen would make this more apparent

^ How do I know what date timeframe I'm looking at?
