 				<li>The above menu bar takes minimal vertical space and as much horizontal space as possible. On smaller displays, items get moved outside the screen and can be reached simply via scrolling.</li>
 				<li>You can open as many new tabs as you want, pointing to whatever URL or uploaded file content, but <a href="https://developer.mozilla.org/en-US/docs/Web/API/Storage_API/Storage_quotas_and_eviction_criteria#web_storage">keep in mind that your browser may limit the amount of storable data</a>.</li>
