Build #4 (#3 had a bug): Now the build toolkit generates a secure platform key for signing the build, and also includes BlissView (frameworks integrity validation service), along with Bliss Display Mapper, and moving them all (Including BlissTouchMapper) into Settings > System (like the other Lineage Extra Settings apps).
MicroG is also included and working (updated vendor/foss & vendor/foss_userapp for A14+) in this version. Next build will be adding some finishing touches (bootanimation and wallpaper customization options, and a few other features)
