Also documentation (related to this topic) is now in right state of mind: https://docs.armbian.com/User-Guide_Armbian-Software/#adding-example
It is hard to add software title we never tried, installed and / or know nothing about, then expert user of this software adding it to (armbian-config) installer. We focused to make this task as simple as possible, to encourage you doing that and not opening us tasks (we already have 1000 x too many and won't ever complete).
We added popular titles to the system, which have some value for us, while everything else is mocked by more important tasks in other sections.
But mechanism is there - use it, its user / developer friendly. Also its a nice and easy way to contribute to the open source.
