Snaps Of Apps — Release Notes (v1.10)

Robust multi-display restore

Rock-solid multi-display restore — Windows now reliably restore to the correct monitor using robust screen attribution and a safer restore pipeline.
Smarter screen attribution (save) — Uses CoreGraphics display bounds with a configurable primary rule (center-in-bounds or largest overlap) plus nearest fallback to assign the correct display when capturing.
Stronger target screen resolution (restore) — Matches displays by exact saved bounds first, then nearest origin, then ID, then closest size to resist ID flips and cable swaps.
AX/AppKit conversion fixed — Coordinates are now converted relative to the main display's top-left (not the desktop union), preventing main-screen snapping.
Strict screen enforcement (optional) — A center-hop to the destination display before final placement helps stubborn apps land on the correct monitor.
Better window selection — For apps with multiple windows (Chrome, VS Code, etc.), the chosen window is now scored by title match and screen proximity.
Display remap UI (when screens are missing) — Presents a 10.15-friendly modal panel listing all connected displays with OK/Cancel and clear suggestions.
Grouped, readable logs — Save/restore output is grouped by display name with blank-line spacing; per-app restore sections are also separated for fast scanning.

Fixed windows restoring to the wrong monitor after sleep/reboot or cable swaps (bounds/origin matching + corrected coordinate conversions).
Fixed cases where only the Built-in display appeared in the remap prompt; all connected displays now appear consistently on macOS 10.15.
Fixed AX timing issues for apps like Microsoft Teams by polling for windows (and falling back to main/focused window) before restore.
Fixed incorrect Y-axis and union-frame math that could cause off-screen placement or main-screen snapping.
Fixed screen ID persistence issues by storing CGDirectDisplayID as unsigned bits in Core Data to avoid sign extension.
Fixed quit flow logging and spacing; added detailed per-bundle termination results.
Removed ambiguous CF downcasts; CoreFoundation type checks are now explicit for clean builds.

UI-only capture: background agents and excluded bundle IDs are filtered out when saving snapshots.
Restore is non-destructive: remap choices are session-only and never modify saved snapshots.
Per-display grouped logs include monitor names and both calculated and resulting rects for easy diagnosis.

macOS 10.15+ — All features, including the remap prompt, work on Catalina and later; Preferences use 10.15-safe APIs.
Backward-compatible snapshots — Existing snapshots continue to restore; older entries without saved origins fall back gracefully.

Version: 1.10
Release Date: October 20, 2025
Minimum System: macOS 10.15 (Catalina) and later
Highlights: Robust multi-display restore, 10.15 remap UI, strict screen enforcement, grouped logging

No migration required. Your existing snapshots will continue to restore; new captures benefit from improved display attribution and persistence.
Optional preferences let you tailor capture heuristics (center vs overlap) and enable stricter restore behavior when needed.
