The app is not designed for elemental, its designed for any kernel and device. No need to uninstall it. It works fine with stock or any other custom kernel (except boeffla, which changes all the sysfs paths)
Like all of my kernels and apps, EXKM is completely noninvasive. It will not change or modify your system in any way unless you specifically tell it to.
Which is EXACTLY the reason why I told him to uninstall it. He wanted to get back to the previous situation and configuration with ABSOLUTELY no issues. I know that your app isn't exclusively for your kernel, and can change the stock kernel configuration. So uninstalling it is the best solution.
