v0.19.1 - Experimental Windows release

TrueTrack 0.19.1 — Crosshairs and clearer calibration

• Customize your in-app crosshair: six shapes, six colors, size, centre gap and thickness, with a live preview.
• New calibration baselines use a subtle moving dot field. Free practice retains the 3D room.
• Wider flick scoring area, smaller 100-point bullseye, and 99–1 points outside it.
• Thicker progress bars and larger calibration instructions with fade transitions before timed measurement.
• Separate post-exercise precision timing summary flags successful hits above twice the median as possible distractions. Raw measurements and all profile acceptance checks retain every attempt.
• Updated algorithm documentation and screenshots.

Start a new baseline for the new targets and background. Existing rounds retain their geometry, background and crosshair so comparisons remain consistent. Crosshair preferences and measurements remain in the local data folder during updates.

Extract the full Windows ZIP and run TrueTrack/TrueTrack.exe, or use History / updates. No driver is installed and no profile is activated by updating.

Validation: 443 automated checks passed, visual inspection of the new views, and packaged-update preservation verification. Experimental and unsigned. Global crosshair overlay and real-time correction of unwanted curves are not implemented; actual polling rate, presented FPS and monitor refresh rate are not yet measured.
