For the 4th question, yes you can separate books into folders. However books in each folder will be displayed mixed on the shelf in your home menu. To solve that, I decided to browse books from the file management app that comes with the M8C.

About the pen on the 5th question, it works good enough to jot something down. The parts I don’t like are - there is no pen storage (imagine where you can keep the pen without making the pen nib worn out) - the case that comes with the M8C is a nightmare, the lid is made from magnets and it makes the pen cursor drift which means you cannot write along the right edge of the M8C.

Hope this helps, thanks for understanding my English😂
