Universal Save & Copy Shortcuts
Effortlessly capture web content without interrupting your flow. With globally recognized keyboard shortcuts (Command + Control + S to save, Command + Control + C to copy the current URL), you can instantly send any link from any major browser directly into your SupaSidebar. This eliminates the tedious process of copy-pasting into separate note-taking apps or managing a chaotic bookmark bar, keeping your research and resources neatly organized in one dedicated, accessible space.
Recents & Favorites for Instant Recall
Never lose track of your work again. The "Recents" section automatically tracks every website you've visited in the last 48 hours, acting as a short-term memory for your browsing. For your essential tools, the "Favorites" (pinned items) feature keeps your most-used links, files, and apps permanently anchored at the top of the sidebar. This combination ensures that whether you're returning to yesterday's research or launching a daily dashboard, everything is just one click away.
Fast, Unified Search (CMD + CTRL + K)
Break down the barriers between apps and files. By pressing Command + Control + K, you activate a powerful, instantaneous search across your entire SupaSidebar library.
