Haha, I just finished the new version with just that feature. It also supports hiding the recommendations from the home screen, since many people wanted this in the future firmware feature request thread.
If you have more ideas of what to add/alter please share them.
The installation procedure is the same as above.
@ah-: is there a chance that I could commit my changes to your git repo.
Of course! I don't have too much experience with github since until recently i just directly used git with my own server, but I guess the way to go is that you create a github account, fork the repository and then send merge requests for individual commits. Maybe we could also setup github so can directly commit to my repository, but I'm not sure how that is done.
Please feel free to improve everything.
Oh, and before I forget it: I think we should come up with some simple deinstallation procedure if we start to distribute the plugin as easily installable zips. Just deleting it via ssh is easy, but not everyone has that set up. Maybe flashing some other file so the original gets overwritten, or some script that automatically deletes it. I don't want anyone to have problems because of the plugin if the Kobo firmware should ever update itself and change the interfaces.
Also checking the firmware version on load might be a good idea. And lastly, the qtscript plugin is potentially dangerous if you're not in a network you trust, since it's only intended for development and uses no authentication. Libtweaks.so works fine without it, so don't install the qtscript plugin if you don't know what it does.
