I'd also like to thank Joel Goguen, the maker of 2 extensions (in Calibre) I could not live without :

Kepub Output : converts on the fly Epub to Kepub, which lets you benefit from the stats while reading.

Kobo TouchExtended : which lets you create and manage your collections on the device (by tags for me.)

I also added the tweak that can make available full page, without header and footer.

How to Enable Full Screen Mode

1. Plug your Kobo ereader into a computer with a USB cable and enter computer transfer mode.

2. On Kobo devices there’s a folder called Kobo eReader.config. It’s located on the Kobo drive in the .kobo folder inside the Kobo folder.

3. Right-click on the Kobo eReader.config file and choose to open it with a basic text-editing program like Notepad.

4. Add the following code to the file at the bottom, or anywhere as long as it’s separate from the other code:

[FeatureSettings]
FullScreenReading=true

5. Safely eject your Kobo ereader from the computer. Then open the settings menu and go to Reading Settings. There’s now a checkbox to show the header and footer.

* Depending on the ebook, sometimes full screen doesn't work as expected. Then, you have to disable full screen. But it works fine most of the time.
