#!/usr/bin/env bash

# Print useful information about the window node by retrieving data from bspwm, X11 and Process Info (PID, RAM, CPU)
# Also displays it via notify-send
# Recommended usage: Add a keybinding in sxhkdrc to execute this script and run it only on the currently focused window to receive a notification with useful node information
# Requirements: bspwm (bspc), jq, xprop (x11-utils), notify-send (libnotify), servidor X11
