Hello, I have to say memmy is far superior to the official interface. Brilliant thanks for making it.
Maybe I would suggest getting rid of the 3 button layout and reducing it to 2 if possible. Right top seems way too full. 
Especially the 3 dots show only 1 option. So the last 2 can be imho merged.
I agree that the three buttons don’t make a huge difference, but I also don’t think users will swap between compact and card view often enough to warrant a permanent fixture on the top of the screen.
I personally would place it in settings under Appearance.
I also don’t disagree with that!
