CarHome Ultra and general landscape questions

[StealthPope]

Hi, I just picked up my S4 from Verizon, and I ma wondering how do I get the thing into landscape mode when on the home screen? I can do it from withing apps, but not on the home screen. Also, is there any hack or way to get the car mode to choose CarHome Ultra as my car mode? I came from a Razr Maxx and really enjoyed the car mode functionality.
