#### Live X11 XQueryTree hierarchy, EWMH atom, and window attribute inspector

Inspired by classic X11 window tree and attribute inspector utilities.
Independent open-source Linux tool, not affiliated with any third-party vendor.

FEATURES
• Crosshair Window Picker & Live XQueryTree Hierarchy: click any X11 or
XWayland window with an interactive crosshair cursor or browse the full
parent-child XQueryTree hierarchy with instant XID, WM\_CLASS, and PID filters.
• EWMH Atom & Property Decoder: enumerate attached X11 atoms via
XListProperties and inspect WM\_CLASS, \_NET\_WM\_PID, \_NET\_WM\_STATE,
\_NET\_FRAME\_EXTENTS, WM\_PROTOCOLS, and WM\_NORMAL\_HINTS values in real time.
• Live XClientMessageEvent & Geometry Controller: apply move\_resize bounds,
toggle above, shaded, sticky, fullscreen, or maximized states, adjust window
opacity, activate windows, and export JSON or CSV inspection snapshots.
• Bilingual UI: starts in English by default with instant Vietnamese toggle.
