please push it upstream so it's official part of LibreELEC.
It is already: LibreELEC.tv/projects at master · LibreELEC/LibreELEC.tv · GitHub
P.S. Now I'd like to copy it from microSD to internal EMMC as it will be my main HTPC player now (bye bye Raspberry Pi!). I'll try to find some instructions for that. Then I'll see if I can get sleep and wake-up working
Install to eMMC is not supported yet, although with a bit of Linux knowledge, you can do it already by executing some commands. There are some ideas how to make user friendly eMMC installer, but nobody is working on that ATM.
about sleep and wake up - that's more complicated and depends on what you mean by wake up. Is this just a power button press? that is probably easy to achieve (but not much lower power consumption). If you mean wake up by IR or even HDMI CEC, that is much more complex, because is needs special firmware on low power coprocessor, to actually wait for signal and wake up main cores. Such firmware is actually in the works (crust-firmware on github), but I'm not sure when it will be good enough to use/integrate here.
