Window Pin and PiP Tool

A Linux X11 alternative to WindowTop. Independent open-source project, not
affiliated with or endorsed by BiGilSoft.

Window enumeration, Always-on-Top (NETWMSTATEABOVE), window opacity,
XShape input click-through, and live Picture-in-Picture capture operate on
X11 and XWayland windows; Wayland-native windows cannot be controlled by
external X11 clients, and an X11 compositor is required for per-window
alpha transparency.

FEATURES
• Always-on-Top, Opacity & Click-Through Ghost Mode: inspect live X11
windows, toggle NETWMSTATEABOVE, set NETWMWINDOWOPACITY
(25%-100%), toggle XShape input click-through, and apply translucent
Dark / Night / Warm / Invert tint overlays.
• Live Picture-in-Picture (PiP) Clone & Crop: spawn resizable frameless
Always-on-Top PiP windows streaming live QScreen.grabWindow captures at
5-20 FPS with full-window or custom crop-rectangle selection and
click-to-jump back to the source window.
• Auto-Pin Rules & Global Hotkeys: assign XGrabKey global shortcuts and
persistent wildcard/regex title or WM_CLASS rules, with automatic
opacity and click-through restoration when exiting.
