Did I mention the X4 lately? ^^
I recently concluded that Crosspoint could benefit from a few more customizations and more font size options offered in Papyrix. It turns out that Inx might be the firmware to fill the gap. It also displays your current reading time, along with the number of pages and chapters—quite a nice feature!

Still in pre-release, so very promising. I just didn't see an option to prevent the display fading effect when the X4 is exposed to U.V. It could be activated by default or not implemented.
