ScreenToSpace v15

Highlights

• Added GNOME Shell 50 compatibility.
• Added a safer Place next to current workspace mode.
• Added support for manually entering custom app IDs/window classes in the filter list.

What’s New

• Safe adjacent workspace placement

  • New optional setting: Place next to current workspace.
  • When enabled, ScreenToSpace tries to move isolated windows to an existing empty workspace directly after the current workspace.
  • If that placement is not safely available, it falls back to the standard workspace placement behavior.
  • Includes per-window cooldown/tracking to avoid repeated placement loops and CPU spikes.

• Custom app/window-class filtering

  • The App List UI now allows manually entering app IDs or window classes.
  • This makes it possible to blacklist/whitelist windows that do not appear in the app picker, such as gjs windows used by Desktop Icons NG.

Fixes

• Fixed cases where blacklisted apps could be moved before GNOME exposed their app ID.
• Improved handling for fullscreen/maximized windows during close/destroy events.
• Avoided unstable app/window lookups while Mutter is unmanaging windows.

Notes

The adjacent workspace mode is intentionally conservative: it reuses existing empty workspaces and falls back automatically instead of force-creating workspaces. This keeps the feature safer on GNOME dynamic workspaces.

V8.0.0

🎯 What's New in v8

Application Filtering System

The biggest addition in this release—per-application blacklist and whitelist modes requested by the community (#4 ).

Features:

• Blacklist Mode (default): Exclude specific apps from workspace isolation (e.g., Telegram, WhatsApp, IDEs)
• Whitelist Mode: Only manage explicitly listed applications; all others stay in current workspace
• Multi-Select App Chooser: Select multiple applications at once with checkbox UI
• Real-time Search: Filter through installed apps instantly while adding to lists
• Smart ID Normalization: Reliable app matching with automatic .desktop suffix handling

UI/UX Improvements

• Three-Tab Preferences Layout: Separated Settings, App List, and About into dedicated tabs
• Native GNOME Design: Built with libadwaita (Adw) widgets for seamless integration
• Live Updates: App lists refresh automatically when adding/removing applications
• Modern Icons: Tab navigation with themed symbolic icons

Technical Improvements

• App ID resolution with fallback chain (gtk_application_id → wm_class_instance → wm_class)
• GSettings schema extended with filter-mode, blacklist-apps, whitelist-apps keys
• Modular architecture: WindowFilter handles all filtering logic separately from placement
• ID normalization for consistent matching across different window types
