Scrollify is a small Windows tray app that adjusts Spotify's Windows volume-mixer session with Alt + mouse wheel.

Behavior

• Alt + wheel up increases Spotify's volume.
• Alt + wheel down decreases Spotify's volume.
• Left-clicking the tray icon enables or disables Scrollify.
• Right-clicking the tray icon opens or closes the settings panel.
• Mouse input always continues to the active application.

Scrollify changes only Spotify.exe audio sessions. It does not inspect or modify other processes, switch windows, or generate input.

Requirements

• Windows 10 or 11
• Spotify for Windows
• Microsoft Edge WebView2 Runtime

Build

cargo build --release

The portable executable is created at:

target\release\scrollify.exe

Icons and panel assets are embedded in the executable.

Shortcuts

On launch, Scrollify creates or refreshes this per-user Start Menu shortcut:

%APPDATA%\Microsoft\Windows\Start Menu\Programs\Scrollify.lnk

This makes Scrollify searchable in Windows and allows it to be pinned to Start.

The Start with Windows setting manages:

%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\Scrollify.lnk

No administrator privileges are required.

Configuration

Settings are stored in:

%APPDATA%\Scrollify\config.json
