Default [Q] LG G2 Window case ROM support

Hello, Today I bought my new LG G2 for Verizon and I got the window case for it. I'm really loving the phone itself however I don't like LG's ROM that much. I would like to install another ROM but I would like to preserve the smart window case feature because it is really handy. I searched around and found another thread about this same topic but there were only three posts in it and it looked abandoned. So basically I want to know if anybody knows of a ROM that preserves this feature, any help is greatly appreciated thanks in advance
