First of all, many thanks to Morkl for the great work, highly appreciated!
After having run my T1 rooted for many months, using a very basic way to get a font of my choice, my battery started to get drained quite fast. I did not use the possibilities of the root any longer (only reading for months), plus, I noticed, that the reader now shows a clock, thus I decided to take the plunge, unroot and install this reader.
IT WORKS GREAT!
It only was a bit hard to find all the information I needed, as it is scattered all over the place.
Whatever was relevant to me, i now put into a new wiki page, dedicated to this reading app, hoping that this might provide some sort of basic documentation for beginners.
Feel free to change/add to your heart's content:
