Why Dimming One Window Isn't Enough (2026)

Window dimming tools have been around for years. HazeOver on Mac, FocusDim on Windows. The idea is simple: darken everything except the window you're using. It works well for single-window tasks like writing a document or reading an article.

But most real work doesn't happen in one window.

Developers keep a code editor, terminal, and browser open at the same time. Designers jump between Figma and reference images. Accountants flip between spreadsheets and a calculator. Dimming to a single window hides the other windows you actually need.

FocusDim v1.5 fixes this with three highlight modes and automatic drag escape. Here's what each one solves.

Problem 1: Multi-window workflows

You're working in VS Code. You have the editor on one monitor, a terminal on another, and the VS Code settings panel floating. Standard single-window dimming picks one of those and dims the rest. Now you can't see your terminal output while you type.

The same thing happens with Chrome. You might have localhost on one tab-window, the staging site on another, and the docs open in a third. Single-window dimming forces you to toggle it off every time you switch between them.

Fix: App Windows mode

App Windows mode keeps every window from the same application visible. Click any Chrome window and all Chrome windows stay at full brightness. Switch to VS Code and all VS Code windows light up instead.

The dim still blocks out unrelated apps. Slack, Spotify, File Explorer, anything that isn't part of your current app stays dimmed. You get focus without losing context.

Problem 2: Drag and drop between apps

You need to drag an image from File Explorer into a Slack message. Or move a file from Downloads into a project folder in VS Code. With window dimming active, the target window is dimmed. You're dragging blind.

HazeOver's workaround: press the fn key while dragging. You have to remember the shortcut, hold it down, and release it after. It's clunky.

Fix: Drag Escape

FocusDim detects when you're dragging a window by its movement. The dim fades out automatically. You can see every window on screen, pick your drop target, and let go. The dim fades back in on its own.

No keyboard shortcut. No button to hold. Grab a window, the dim disappears. Drop it, the dim returns. It also works when you're resizing windows.

Problem 3: Desktop clutter without app clutter

Sometimes the problem isn't other apps. It's the desktop itself. Wallpaper, taskbar icons, pinned shortcuts, notification badges. You want to see all your app windows but block out the desktop background noise.

Fix: All Windows mode

All Windows mode dims only the desktop and taskbar. Every application window stays at full brightness regardless of focus. This is useful when you're referencing multiple apps on multiple monitors and don't want visual clutter from the desktop behind them.

It's also the simplest mode if you just want a clean background while working. No per-app logic, no tracking which window is focused. Everything stays visible except the desktop.

These features are FocusDim exclusives

HazeOver on Mac has "highlight all windows of same app" (similar to App Windows mode). But it doesn't have All Windows mode or automatic drag detection. Those are only in FocusDim.

You can switch between highlight modes from the system tray menu or the settings panel. The change takes effect instantly, no restart needed.
