## Privacy

AltTab doesn’t communicate to any server for so-called telemetry. AltTab will only use the network if it's absolutely required (e.g. checking for updates).

## Performance

AltTab has been designed to take as few resources as possible on the user computer. The app itself is kept as small as possible. CPU usage is kept to a minimum, especially while in the background. The goal is to respect the user and try to have no negative impact on their experience.

## Configuration

Change the shortcut keys, switch to a Windows theme and more, using the Preferences window:

<div class="can-extend" style="display:flex; align-items:center; flex-wrap: wrap;">
    <a href="public/demo/preferences-general.jpg"><img loading="lazy" src="public/demo/preferences-general.jpg" alt="Screenshot: General preferences" width="672" height="354" style="width:100%; height:auto; max-width:330px;" /></a>
    <a href="public/demo/preferences-controls.jpg"><img loading="lazy" src="public/demo/preferences-controls.jpg" alt="Screenshot: Controls preferences" width="677" height="688" style="width:100%; height:auto; max-width:330px;" /></a>
    <a href="public/demo/preferences-appearance.jpg"><img loading="lazy" src="public/demo/preferences-appearance.jpg" alt="Screenshot: Appearance preferences" width="672" height="735" style="width:100%; height:auto; max-width:330px;" /></a>
    <a href="public/demo/preferences-appearance-details.jpg"><img loading="lazy" src="public/demo/preferences-appearance-details.jpg" alt="Screenshot: Appearance preferences (details)" width="672" height="934" style="width:100%; height:auto; max-width:330px;" /></a>
    <a href="public/demo/preferences-blacklist.jpg"><img loading="lazy" src="public/demo/preferences-blacklist.jpg" alt="Screenshot: Blacklist preferences" width="672" height="655" style="width:100%; height:auto; max-width:330px;" /></a>
    <a href="public/demo/preferences-policies.jpg"><img loading="lazy" src="public/demo/preferences-policies.jpg" alt="Screenshot: Policies preferences" width="672" height="353" style="width:100%; height:auto; max-width:330px;" /></a>
</div>

## CLI usage

You can run CLI commands directly on the executable inside the .app bundle (e.g. `/Applications/AltTab.app/Contents/MacOS/AltTab`)

* `AltTab --list` will return the list of windows (ID and title) in JSON
* `AltTab --detailed-list` will return the list of windows (lots of info) in JSON
* `AltTab --show=shortcut_index` will show AltTab UI, as if the corresponding shortcut was pressed
* `AltTab --focus=window_id` will focus the window with the specified ID (get it from --list)
* `AltTab --focusUsingLastFocusOrder=focus_order` will focus the window with the specified focus-order (get it from --detailed-list)

For this to work, you need AltTab.app to be running, to keep track of the state of windows, and execute the commands

## Alternatives

Before building my own app, I looked around at similar apps. However, none was completely satisfactory so I rolled my own. Also, the almost-good-enough apps are not open-source.
