Hi! Well, my library is fully imported and tagged into Calibre. I am just trying and I have been able to send books to my Kobo, both ePub and Kobo ePub. I have read a few pages and I like it. It's comfortable, perfect size, dictionary is better than Kindle (and you can search again on the definition...). So far so good but I have more questions than ever.
- The first thing I notice is that the Kepub and ePub books are rendered quite different despite having the same font size and margins on the Kobo. Is this right or did I mess up with Calibre settings? Left image is Kepub and right is ePub.

- I can't see any statistics with ePubs. Is this normal? The little bar that appears right-up corner with Kepubs doesn't shows with ePubs. I also noticed that sometimes, both in ePubs and Kepubs, current page number doesn't always change with each page turn or flip.
- I see that font, margins and spacing customization are saved individually by book. This is the opposite of Kindle because with Kindle it applies the changes to every book on the device. I understand that this is a normal behavior in Kobo software, right?
- When I go to the book details on the Kobo (I click the 3 dots then "See details"), there are to tabs to see the synopsis and the file details. In the synopsis there is a weird double spacing despite having it right on Calibre. If a check a book on the Kobo Store it happens too (despite showing right the first second it is loaded and then change to show double spacing), so I am assuming it's the way it is, right? First picture is a my book in my library and the other two when I open a book on the store and how it changes a second later.

- Last, it is possible to show things like tabs or ratings on the details section if I add them to Calibre?
Thank you. Your help means a lot.
