Universal Browser Integration & Capture
SupaSidebar seamlessly integrates with all major web browsers, including Safari, Chrome, Arc, Firefox, and Brave. This allows users to capture or copy the current webpage URL from any browser instantly using dedicated, configurable global keyboard shortcuts (e.g., Command+Control+S to save, Command+Control+C to copy). This feature eliminates the cumbersome process of manually bookmarking or copying links across different platforms, centralizing web resource management into a single, always-accessible hub.
Intelligent Recents & Favorites Pinning
The application automatically tracks and displays every website accessed across all integrated browsers within the last 48 hours in a "Recents" section, serving as a powerful short-term memory aid. Users can pin frequently accessed links, files, or folders as Favorites, which are permanently elevated to the top of the sidebar for immediate, one-click access. This dual-system organization ensures both recent context and critical daily tools are always at hand, drastically reducing search time.
Global Instant Search (Command+Control+K)
Activating the universal search shortcut (Command+Control+K) opens a powerful search interface that indexes and retrieves items from across all saved links, files, folders, and applications in real-time. This feature enables users to bypass manual navigation entirely, finding any resource by name in seconds. It is engineered to minimize cognitive load and maintain workflow momentum, acting as a central command center for all digital assets on the Mac.
