Well, I've updatd my Glo in 4.3.8832... I've still have the old home screen but it's not a problem.
I've add this line in the config file in order to use the nightmode plugin :
[FeatureSettings]
InvertScreen=true
And it works !
But 3 things :
1. with the old nightmode plugin I was able to jump between daymode (white screen) and nightmode (black screen) with the light button doing a long press on the light button.
Now how can I do to switch between the 2 modes ? I can't find a toggle under "Reading Settings" ! for devices who have a physical button to turn on the light, it could be a good thing to keep the ancient solution : a short press turn on/off the light, a long press switch between the day/night mode...
2. If I completely stop and start my device : the night mode is used (it's the InvertScreen=true setting seen before). If I go to sleep mode, the night mode dissapears and it require a new stop and start to come back !!!
3. If I go to sleep mode twice, I have got an empty screen... perhaps it doen't come from the nightmode feature
?
Here is a video where we can see the point 1. and 2. :
