The kobo firmware has some undocumented or experimental features that are not active by default, but which can be enabled in the [FeatureSettings] section of the device's configuration file
.kobo/Kobo/Kobo eReader.conf.
The configuration file is a plain ASCII file with unix line breaks. When editing it,
it is important to use an editor that doesn't change the file type or line break style. Most Linux and Mac text editors should be okay, but
don't use Notepad or Wordpad in Windows: use an editor such as
Notepad++ instead.
(Enabling these features doesn't require patching at all, but some patches work in conjunction with undocumented features, so I've included this post here for reference.)
An example of an undocumented feature is
FullScreenReading which, once enabled, adds the following option to the Reading settings menu:
To enable a feature, e.g. FullScreenReading, edit the configuration file and add the new feature to the [FeatureSettings] section. (If there is not already a [FeatureSettings] section, then add that too.) The result should look like:
Code:
[FeatureSettings]
FullScreenReading=true
Additions to [FeatureSettings] will remain in place after a firmware update. If you want to disable the feature you can edit the configuration file again and change its setting from true to false.
