Small detail, I've noticed some root apps not working anymore (sshd server app, LMT Launcher in my case).
In fact, turning SELinux to permissive made that work again.
Next update will allow to set SELinux to your needs from Aroma. (You also can do this using an app in PlayStore, don't know if it does this on boot, though)
Something else, that is in the pipeline ...
Currently working on touchwake (not doubletap2wake), which should be seen as a "touch the screen whenever it times out in the next x seconds to turn it on again" and not as a "power button replacement".
Keeping the digitizer active on the Nexus 5 requires keeping the display pannel powered (not backlight, just the actual LCD pannel), which will and does drain battery, so I'm not too cool with that.
But keeping those active for a few seconds after screen times out isn't a big issue and won't be noticable on the battery, thus totally acctepable.
The touchwake will still allow to be used as tap (or doubletap, it's switchable) to wake (power button replacement) by setting the delay to infinite, so whoever wants, can, but as I said, I'm not recommending it.
There's still work to be done, so far I've put quite a few hours, starting off of showp's dt2w, stripping off everything I didn't need (sweep2wake etc.). I've added user configurable precision (max. distance between first and second tap to be considered a doubletap) and speed (max. time between first and second tap to be considered a doubletap), so you can set this to your liking to avoid accidental doubletaps.
It's work in progress, I still need to finish the delay (turn off digitizer to stop battery drain after x seconds), including a powerkey poweroff detection (which would not trigger touchwake, this will be switchable, too, as in dt2w it makes sense to keep it working even if using the powerkey to switch off the device). And mostly, I need to add proxy support, as to disable touchwake whenever the device if close to your ear (as in-call detection).
So don't expect this to pop today or so, it's workweek again, and there's a lot going on at work atm. So I'm often not keen to go coding in the evening
Also I will likely be including another governor as well, but one thing after the other, one step at a time as they say...
