Hi skanky,
no, to answer your question, I haven't made any documentation for the files I've played with. I suppose ultimately, Together Jolla would be the place for such a wiki, or here on TMO..??, suggestions welcomed.

Anyway, the files I played with are all found in /usr/share/themes/jolla-ambient/meegotouch/icons

• graphic-background.png
• graphic-gradient-corner.png
• graphic-gradient-edge.png
• graphic-gradient-home-bottom.png
• graphic-gradient-home-top.png
• graphic-shader-texture.png
• graphic-system-gradient.png
• graphic-texture-pyramid-diffuse.png
• graphic-wallpaper-dimmer.png

All I did was to chmod each file and then rename using '.old' as the extension.
I am aware that the way I edit/rename files is perhaps not the way others do it, but it works for me until I learn to use 'nano' or 'vi'.

Renaming the above files was purely an experiment to see the outcome, the effects might not suit everyone, but for me with fairly crap eyesight, I now find the Jolla screen looks sharper in general and the phone even feels a little faster to operate - YMMV.

The other file,(main.qml - found in /usr/share/lipstick-jolla-home-qt5) as discussed earlier in the thread, I'm still playing with. The outcome so far, is not what I expected but it did remove the black background of launcher but left the ambience static and very heavily obscured - this is as far as I have played with this file (I have already crashed the phone once today, doh!)

Please note: I guess some will not see this post as a list of tweaks and I would be inclined to agree, suggestions to change/move the post are welcomed.

Regards,
