I've been installing the CM11 nightlies and really like them. I haven't had any serious issues with them and I am excited about a stable version coming out. While having both a stock ROM and CM11 installed I have not figured out how to get the apps installed for both ROMs. They seem to tell me that it is already installed, or they will try to open but close immediately. I was wondering if there was some way to have them installed and working for both ROMs, or if I will need to replace my stock ROM with CM11, and how exactly would I go about doing that?
