+			<h2>Usage and Help</h2>
+			<p>
+				This app exists because I needed an efficient interface for visualizing specific websites, HTML data in general,
+				and allow for even novice users to handle data shared this way.
+				<br/>
+				Being itself a webapp, unfortunately it isn't a replacement for any web browser, but that isn't its goal.
+				This is instead made to be as cross-platform, lightweight, flexible and immediate to use as possible.
+				A webpage working with iFrames, that can even function offline, has revealed itself to be the best possible option.
+				<br/>
+				In the past I planned to introduce some fancy features like split tabs, but for now I don't yet know... stay tuned!!
+			</p>
+			<p>Some tips:</p><ul>
+				<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>
+				<li>You can go back to this info page at any moment by clicking "Root Window" in the Tabs menu.</li>
+			</ul>
 			<h2>Changelog</h2>
 			<h3>2024-03-19</h3><ul>
 				<li>Remove info button from toolbar for now.</li>
+				<li>Update info page also adding Usage and Help section with tips.</li>
+				<li>Fixed interference between frame zoom and menu hiding features.</li>
+				<li>Slight improvements to the UI (buttons and margins).</li>
 				<!--<li>Make current tab not persist after reload if changed when opened from hash flags.</li>-->
