Halo-v1.1.0.zip

All notable changes to Halo are documented here. The format follows Keep a Changelog, and the project adheres to Semantic Versioning.

Drag-to-reorder buttons within the tray (grid mode); order is saved. A ghost icon lifts and follows the cursor while the other tiles glide to open a gap at the drop slot (midpoint targeting), then the ghost flies into place and fades.
Shared eased-tween engine (UI/Animation.lua) powering the drag/drop motion.
Radial layout mode — buttons orbit the launcher in a ring.
Search box that appears once 10+ buttons are collected and filters the tray.
Profile management UI (create/switch/copy/delete) via AceDB profiles.
Masque skinning support for the launcher button.
Options to opt specific Blizzard minimap frames into the tray: Looking For Group, Mail, Tracking, and Battlegrounds (off by default).
/halo scan diagnostic listing every collected button's render state.

Collected buttons now render inside the tray instead of behind it (LibDBIcon locks its buttons' frame strata via SetFixedFrameStrata; Halo unlocks them and the tray sits at MEDIUM strata to match).
Buttons no longer escape back to the minimap (Halo takes sole authority over an adopted button's SetPoint).
Layout is fault-tolerant: one problematic button can't abort the whole tray.
Quest pins and small map markers are no longer collected (20px size floor).

Single minimap launcher (LibDBIcon) that gathers all other addon buttons.
Detection of both LibDBIcon buttons and legacy hand-parented minimap buttons, including buttons that register after login.
Animated flyout tray with a flat, modern dark theme (fade + scale, hover highlights, soft shadow) laid out in a reflowing grid.
Custom settings panel via the modern Settings API: columns, tile size, spacing, open-on-hover, auto-hide, tray opacity, tray scale, and a per-button opt-out list.
Lossless release: opted-out buttons return to the minimap with their original anchors intact.
Slash commands: /halo, /halo config, /halo reset, /halo help (and /hl).
Headless CI: luacheck plus a mock-WoW load test that simulates a full session.
BigWigs packager release workflow.
