I've installed CoolReader (or better the menu launcher with Chess, Sudoko & all) again in my Kobo Aqua as I was annoyed by the fact that it did not read .rtf correctly! Now the book that suddenly stopped with the Kobo reader is perfectly readable, it has a real TOC and in the first pages I have images that was not shown! Fantastic!
I have noticed that CoolReader cannot read neither PDF neither CBZ/CBR it is not possible to add the support for them? Or add specifics readers for these formats?
There is a file manager application but it seems I cannot open book with it could be an interesting compromise to use this application to open the books that Cool Reader cannot read using the default Kobo reader will this be possible?
In this way I can avoid to see the ugly Kobo interface and always use a file manager with the book orderered as I like and not randomly
Another thing how to create an hidden directory so Kobo does not process my books?
