Implemented Features

This document provides a comprehensive list of features, performance improvements, and layout styles implemented in cos-niri-bar.

1. macOS Launchpad App Drawer (`cos-launcher`)

True Fullscreen Overlay: Window anchors span all four screen edges, bypassing Niri's exclusive layout margins.
Bottom Gap Elimination: Configured with a -80px bottom margin to extend the window surface completely below the bar shelf boundary.
8-Column Grid: Tightly structured FlowBox layout (max_children_per_line=8, min_children_per_line=8) with compact spacing (18px row spacing, 16px column spacing) and 48px icons in 72x72 bubbles. This optimizes density to fit more applications on one screen and reduce scrolling.
Dynamic Search Focus: Automatically sets keyboard focus to OnDemand when toggled open and grabs input focus inside the search box, allowing search queries to be typed immediately. Releases keyboard mode to None on close.
Escape Key Dismissal: Configured with an EventControllerKey in Capture phase to intercept the Escape key and slide the window closed immediately, even when text is active in the search entry.
Helper Filtering: Ignores helper configuration binaries and hidden setting options (filtering desktop entries with NoDisplay=true).

Variant D-Bus Parse Correction: Corrected SSID variant-in-variant parsing under NetworkManager to prevent D-Bus variant extraction panics.
D-Bus Wi-Fi Scan CPU Optimizations: Replaced blocking loops with non-blocking polling intervals to yield thread cycles to GLib.
Merged Subprocesses: Combined redundant CLI tool execution forks (e.g. wpctl get-volume and is_muted) into single-spawn queries.
O(1) Bluetooth Connection Checking: Batch filters connections in a single shell command rather than looping info checks.

Dynamic Date Navigation: Allows moving months forward/backward and highlighting the current day.
Animated Dismissals: Synchronized sliding animations matching display refresh rates (up to 165Hz).
Non-Stacking Clock: Restructured the clock update loop to prevent timer stacking leaks.
