Currently not open source but I long have been thinking about open sourcing it.
What's wrong with using GH community features?
It's a side / passion project so no time or budget to build any support or community stuff. I considered GitHub, Reddit and Discord and all have pros/cons.
Nothing technically wrong, but GitHub is primarily a code host, the "code place", if you will. So when people use it for issues/feedback its mostly because they have the supporting source on the side.
