Where it goes
What support helps with.
Top priority
Code-signing certificate
An EV code-signing cert (≈ $300–500 USD/year) so the Windows build ships SmartScreen-clean. Benefits the whole project.
Hardware testing
Buying or borrowing compatible cooler LCD units to confirm behavior beyond a single device.
Linux compatibility
Testing across Debian-based distros, hidraw permissions, udev rules and systemd units.
Documentation
Maintaining install notes, the protocol spec, and troubleshooting guides.
Safety
Donation safety.
