Re Re 1: Yes, I see your point with nested folders. I agree this needs to be improved.
Re Re 2: We will look into custom sorting of folders. Do Quick Links get you any closer to your goal?
Re Re 3: So, the issue with not seeing the sd card can be resolved by tapping “Show SD card” from the 3-dot menu. Then select the SD card name and tap “Select”. You can then read and write to the sd card.
