Hey hey! I love checking the thread for the first time and seeing lots of happy users

You guys are awesome and make it all worthwhile.
As far as the backlight goes I have Lumos pre-calibrated, it is an excellent battery saver! However if you want it brighter you can go into Start->Settings->Lumos->Settings tab and adjust the minimum backlight up to whatever level you want.
I don't know what's up with customization but if it seems to take a while at the very end with the bar going over and over again with the "..." it's safe to just soft-reset, it is finished at that point.
I also don't know what's up with the 'ring & vibrate' function, it's something I'm working on...
Tipharet, if you don't like the glass theme just go Start->System->Manila Tweaks and install the Blue or Green theme if you like
