@ Kartu: You are perfectly welcome!
But you will maybe better use
this localized version. (modified by Kravitz)
And maybe a Icon like in surquizu's
extended kBookIcon.png can be used (See Post #8 in this thread).
But also I noticed, that every new reader extendes kBookIcon.png, so that the PRS+ specific Icons will not have the same index across the several versions.
