Using two sessions side by side is popular, and while you can arrange browser windows to a certain extent, it takes a very large monitor to get two browser windows on the same screen, even allowing some overlap.
Using Ctrl+Page Up/Down or Alt + Tab to navigate multiple tabs or windows is usually the recommendation for browser presentation tools. Additionally, we continue to encourage using the browser zoom/resize tools to use the parts of the screen/tool that are required, utilizing your desktop space efficiently.
Incidentally, over time we will be adding more and more content to CBX screens, since we will have capacity to do that far more than we could with CU*BASE GOLD. There are pros and cons to that, but the overwhelming feedback over the past several years from CUs is that they want more content on fewer screens, not less, and they want to be able to size and magnify the screen to their preference. The compromise is that there’s more scrolling (which is much easier with a mouse that has a scroll wheel), and that monitor size matters more than before.
