What's new in v1.1.0

Everything you wanted, finally working right

A complete overhaul of the UI, resolution picker, security model, and display naming - all in one release.

Complete UI Redesign

Two-pane layout with a floating display sidebar, translucent materials, and edge to edge content replacing the old title bar. It feels native macOS because it almost is.

New

Real Display Names

Shows actual marketing names like Samsung S27F350 or LG FHD instead of generic identifiers. A MAIN badge marks your primary display.

New

More Resolution Presets

9 presets from FHD to 5K, plus separate Width × Height fields for custom resolutions and a quick search bar to filter connected displays.

Improved

Security Hardening

Removed a root-level shell injection vector, fixed the HiDPI disable bug, moved temp files to a private directory, and added input validation to prevent crashes.
