All modern browsers can zoom in and out. You can use this to your advantage in XpressU, so you can see several things at once. For example, your Timeline will be able to display several Thumbs at a time
You can zoom with the CONTROL key and either [ - ] or [ + ] for Zoom Out or In, respectively. If you have a MouseWheel on your mouse, it can also be used.
You also can approach the browser zoom by going to the menu in you browser.
Here's the menu in Chrome. It's nearly the samen in Microsoft Edge and Mozilla Firefox
