From my point of view, I switched to kepubs because they load faster on my device at that current moment and with that current firmware,and maybe optical illusion, i found the txt a lot sharper with kepub compared to epub (Don't know if anyone can confirm that).. there are about 40 books on the main reader,all kepub.
With Kepub I experience that the txt at the bottom is closer to the page xxx of xxx txt then with epub, with epub the footer waisted space is bigger.
But on kepub,there is a big gap at the header that seems impossible to remove so maybe the total amount of txt is the same..
So I try to figure out what is better, upgrade and switch to epub again (meaning that I have to remove all kepubs, switch of the features in the calibre driver to make it..) or keep using kepubs with no possibility to use the full screen anymore...

To bad that we don't know any of Kobo's intentions, will they fix a bug that isn't featured at all ? It must be terrible frustrating to make a patch,that is obsolete in a next firmware version..
It seems my old Sony 650 without any upgrade at all,performs better (Not it's resolution,hell no) and there is no waist of space at all..
I don't use the statistics that belong to kepub..
I think I send a couple of books that are now present als kepub also as epub and try to compare.

Is this valid as extra css, and does it adds the extra css when the kobo extended epub feature is disabled ?
