mHD 0.4.0

This release adds the KeyCast keystroke overlay — a visualizer that shows pressed keys, mouse clicks, and modifier combos in a carousel of rounded pills. It is designed for recordings, streams, and screencasts where viewers need to see what keys are being pressed.

Highlights

  • KeyCast overlay — rounded pill carousel shows pressed shortcuts (e.g. Ctrl+Alt+T), mouse clicks, and modifier combos with smooth enter/exit animations.
  • Typing block (optional, off by default) — single printable characters (letters, digits, space) appear in a fixed-width block with a mini-carousel animation. Characters are resolved via ToUnicodeEx against the foreground window's keyboard layout, so Russian, English, and other layouts show the correct glyph.
  • Configurable layout — choose between 6 positions (top/bottom × left/center/right) and adjust display duration from Settings → General or [keycast] in config.
  • Tray integration — toggle KeyCast on/off from the tray menu, or bind toggle_keycast to any hotkey.
  • Tray clarification — "mhd on/off" renamed to "Key Shortcuts on/off" to make clear it suspends only hotkey processing without stopping the daemon.

Documentation

  • Added KeyCast configuration docs to README (actions, settings, TOML config keys).
  • Updated editor action list with toggle_keycast.

Fixes

  • Settings editor General page scroll area now correctly matches the expanded layout — typing controls no longer clip below the scroll region.

New files

  • mhd-daemon/src/overlays/keycast.rs

Package

  • Windows x64 portable archive
  • No installer required
  • No WebView2 required
  • Built without optional developer-only blackbox

Verification

SHA256 is provided as a separate .sha256 file.

Note

The binary is currently unsigned, so Windows SmartScreen may show an unknown publisher warning on first launch.
