In the Speedreading module of the KOReader, I request if it is possible to grey out the content on the page, and based on the WPM set, the text starts to change color to black font.
I have read somewhere that such functionalities can affect the battery life. I understand that, but its a functionality, that need not be enabled by the users, if they are too concerned about the battery.
