Hello, everyone. I am recompiled latest CoolReader for support of change of temperature of the backlight. It is relevant only to users of PocketBook Touch HD 2 (631 Plus in Russia) and Inkpad 3 (740 in Russia).
The principle is as follows. If you swipe up and down on the right half of the screen, the backlight brightness changes. If you swipe up down on the left side of the screen the backlight temperature changes.
I also changed the extensions.cfg default CoolReader needs to open the files, fb2 and epub. He also replaced the skin for Pocket Book 631 with the skin from dizone (4pda.ru).

Who CoolReader is already installed you can just change the file \system\share\cr3\bin\cr3-pb.app in the book to a file with the same location from the archive.
