Are there any information on the differences between customizations. Like i noticed between the baltic lollipop and the russian lollipop update there is a close all button in the recent apps view.

Is there any way to find out what other differences there are.

What im mist iinterested in is what is the best region/customizion ftf to flash. Would like to know what extras or what apps/bloat each ftf has.

Thank you.
