Keycap and Click Overlay

Keycap and Click Overlay is an independent open-source Linux alternative to
KeyCastOW for floating mechanical keycap visualization, mouse click badges,
and live cursor ripple halos on X11 desktops. It is not affiliated with,
sponsored by, or endorsed by KeyCastOW authors.

FEATURES
- Draggable Mechanical Keycap HUD: Polls X11 keymap and pointer state via
non-privileged XQueryKeymap and XQueryPointer to render tactile 3D keycap
badges with automatic repeat counters (x2, x3) and optional click-through lock.
- Mouse Button Badge & Live Cursor Ripple Halo: Displays active LMB, RMB, and
MMB button states inside the floating HUD paired with an XShape click-through
translucent cursor ripple halo overlay at click coordinates.
- Command-Only Privacy Mode: Shows modifier key chords (Ctrl + C, Alt + Tab),
function keys, and mouse clicks while masking plain character typing so
passwords remain private during screencasts.
- Keycap Themes & Font Styling: Includes PBT Charcoal, Retro Beige, Cyber
Neon, and Dolch Amber presets plus custom keycap colors, fonts, and opacity.
- Privacy Audit Log & X11 Diagnostics: Inspect non-masked shortcut and click
activity with UTF-8 CSV export and live XShape / RandR status readouts.
