The Phantom browser extension can appear in two ways:
Popup mode: Opens in a small window.
Side panel mode: Opens alongside your browser so you can keep Phantom visible while you browse or use apps.
Open Phantom in a side panel
Click the side panel icon (square) in the upper-right corner. Phantom opens on the right side of your browser.
To exit, click the exit icon (two arrows). This closes Phantom.
The next time you open Phantom, it appears in pop-up mode again.
Resize the side panel
Drag the panel edge left or right.
