My wife understands my struggle and just offered me a perfect solution

A paper book..
Well.. we handle both my problems with humor
I give up.. stumbled into the next problem..
In order to get the extended driver working, the basic driver must be disabled.
But then the topic says (startpost of the extended driver doesn't even mention the possibility for an extra css) to put a device name css in the plugin directory of the basic driver made by David.
But.. that one must be disabled... and I have a Glo HD which seems not to be supported by the plugin.
I know this is all going offtopic but that started because I asked if it was possible to patch the device.
I can use Calibre to make a kepub and insert the values of the normal extra_css that the basic driver uses, but then calibre will not transfer that one to the device, only the epubs.. it is all to fragmented.
David and Geoff does a good job and update the start topic to keep it up to date, including Murg to keep his firmware topic up to date, but all the other ones are to fragmented, you must sometimes read 85 pages to find the most updated information.
I give up

there seems no simple way to disable all Hyphenation out of Kepubs by a patch so I have to try to get answers in other topics to avoid the going "off topic" here.
I tried it for the last time here:

Thank you all for being so patient to me.
