2.0

Didact (previously BtnQ) — a tiny menu-bar app to control external monitors over DDC/CI.

Install: download Didact.dmg, open it, drag Didact to Applications. Notarized for Gatekeeper.

Initially built for the BenQ RD280UG; this release adds a Set Up This Monitor wizard that reads a monitor's DDC capabilities, auto-detects the standard controls (brightness, contrast, volume, input, colour temperature, sharpness) and teaches the rest — so it works toward supporting any DDC/CI monitor. Learned profiles can be submitted to the community.

Please report any issues, quirks, or bugs you might find.

If you think something can be easier or more straightforward I will make it happen!
