I have tried the Polish ROM, but missing features made me go back to UK BTU Kitkat ROM.
Unfortunately the Jan 15 ROM is still based on Android 5.0 OS. Google has only fixed the big issues with Android 5.1, so not really worth the time and effort to muck around with another 5.0 ROM.
Yeah I'm also back on the UK KitKat recently after I tried the Polish one. Was hoping this might be different despite it's 5.0 :| oh well, waiting patiently for 5.1
