A place where the community can upload VIAL-enabled firmwares
It is not an insignificant amount of work to port a keyboard to Vial and some skills are required. Would be great to have a site for sharing these. All used options (TapDance, Mouse Keys etc) should be visible (selected by uploader).
Security and functionality is a concern of course. Maybe a report button in combination with a warning that these are community-provided and untested would be enough. The reports may be checked by the community or simply posted on the firmware page, like a comment function.
