I should use more of the

to stressout that I feel no offence. Nothing farer than that.
I wonder why
JBPatch did collect no interest. I think everyone who ist interested in
jailbreaking for whatever reason should be interrested in this hack.
It gave the possibility to change core-functions of an eReader (
layout) and do not waste time playing with gatget-like things like playing chess on an ereader (nothing against it).
In my opinion an eReader should focus on one thing and one thing only:
Displaying text with an maximum on aesthetic concerning layout and fonts. Which is sometimes in the eye of the observer. But then give the possibility to change it your way.
Or at least do not hinder people to find own ways to do that.
Edit:
One word on the revival of the JBPatch:
If I had the knowledge I would be interrested in resurrection. Bad sadly, I'm not able to do that.
In case of SONY readers there has been a similiar patch/framework to make other patches possible with the same idea - not to alter original files but 'wrapping' them with new code which was more or less simple to read, alter and install.
On that framework I was able to contribute an enhanced user-interface with more options.
