There are a lot of customizations for Nexus kernels and with that, a few options for apps used to configure them. The only issue is that you may purchase one of these apps, but if you switch kernels, not everything is laid out the same way. This leaves the choice of dealing with options that don't work or buying another app. This app is meant to solve that problem by offering something a little less visually stunning, but highly flexible to support any kernel. After some testing and verification, I came to realize that this app did not have to limit to Nexus kernels. With a few lines of code, it could support almost any variation of the same features and options and simply disable what isn't supported.
There is a free version attached to this post with the ScriptFusion, Kernel Backup / Restore, and Apply on Boot options disabled. Those items require the full version to function. This version does include a popup on start that will notify you of how to upgrade if you are interested.
