Help with Some Mods on MM 6.0.1

Hi guys i updated my g900f to MM 6.0.1 stock. I have root access.

I want to ask a few things:

1. How can i remove the "power saving mode enabled" notification from the notification pannel?

2. How can i remove the "sd card" notification that comes upon boot?

3. Any way to have message icons in the notification pannel on lockscreen?

4. Enable native call recording?

Thank you
