By default, Koel uses [Gravatar](https://gravatar.com) to fetch your avatar based on your email address.
By hovering over the avatar and clicking the <InterfaceIcon:src="uploadIcon"/> icon, you can select an image file from your computer, crop it, and set it as your custom avatar.
Remember to click Save for the change to take effect.
To remove your custom avatar and revert to using Gravatar, click the <InterfaceIcon:src="timesIcon"/> icon.
At the time of this writing, Koel comes with 17 themes built-in. You can activate a theme simply by clicking on it. The new theme will be applied immediately.

More themes are to be added in the future, along with the ability to create your own theme.
* Whether to show a notification whenever a new song starts playing
* Whether to confirm before closing Koel’s browser tab
* Whether to show a translucent, blurred overlay of the current album’s art
* Whether to transcode music on the fly (mobile only, useful if you have a slow network connection)
* Whether to set your uploaded music as public by default <PlusBadge/>
These preferences are saved immediately upon change and synced across all of your devices.
