I wanted it to have a different rotation from the koreader default. So I tried to change the code a little, it would be nice to have this as a default functionality in the plugin. I also would like to have the possibility of putting a transparent PNG over the clock so it would be possible to have a nice customization over it. here's my fork with the rotation changes, and maybe in the future the png feature too: https://github.com/fvelsg/dtdisplay.koplugin
