What it does
Limits shaking to times when at least one app on your comma-separated watchlist is running.
How it works
Shake It On reads NSWorkspace.runningApplications and matches the localized app name against your terms (case-insensitive substring).
Where to find it
Settings → Only Shake If → App is open matching, then a comma-separated list.
When to use it
Great for 'shake while Zoom is open', 'shake while Final Cut Pro is open', 'shake while Xcode is rendering'.
Tips
- Match by part of the name — 'Final Cut' matches 'Final Cut Pro'.
- Use multiple terms for multiple apps: `Zoom, Teams, Slack`.
