About this extension
"Stop fighting for screen real estate. Sandbox is the ultra-lightweight sidebar that expands your workspace without the tab-clutter.
Whether you're taking notes on a lecture, keeping a reference doc visible while you write, or just wanting to watch a video in a true 'Picture-in-Sidebar' mode, Sandbox makes it seamless. It’s the browser upgrade you didn’t know you needed until you tried it."
The Core Kit:
Instant Side-Load: Load any URL into a retractable side panel with one click.
Tab-Lock Technology: Keep your workspace persistent even when you switch main tabs.
Minimalist UI: Designed to disappear when not in use. No bloat, just space.
