The Libra Mini is extremely cool. I find it hard to use row-staggered boards these days or I would most likely have picked one up by now. It is unfortunate though (or at least, this was true last time I checked) that the mfgr doesn't publicly share the QMK code used to build their firmware, which they are supposed to.
I do have one board with a joystick, the Edingburgh41, a fun variant of the classic Reviung41 with a joystick replacing the semi-useless center spacebar on the Reviung.
I don't think its firmware was ever quite fully baked and it was also impacted by breaking changes in QMK a version or two ago, so I never really sorted out what my best use case for the stick was. I don't think it's a great mousing device (although might work well for scrolling with the right settings). I think the best case might actually be using it for modifier keys or even combinations of modifier keys.
