I was wondering if Voxel is going to include his add-on in future updates or will he keep the add on as a manual installation.
Voxel has said in the past that he prefers to keep the add-on separate from the firmware (i.e. not bundled). I think this makes sense because it allows him to remain focused on the core firmware, and isolates the firmware and add-on in terms of release schedule, support, etc.
It might be cool if the firmware had some kind of "hook" to allow the add-on to be installed/uninstalled easily, but in practice I think the add-on is of interest primarily to more advanced users, so manual install is not a big deal.
