The Panels app developed by Fossor Coding is an alternative to Samsung's Edge Panels, offering features such as custom icon packs, quick search shortcuts, and floating widgets. Users can customize the app by repositioning the trigger point, setting up multiple columns (up to seven), and adding various items to the sidebar, including applications, shortcuts, app pairs, accessibility options, system preferences, websites, floating widgets, folders, contacts, and quick search. The free version allows for three columns and nine rows, while the paid version offers additional capabilities for .50. To customize, users must install the app, grant permissions, and use the View button to set up their panel. A pro tip for efficiency includes keeping a thumb on the screen after swiping in to quickly select and launch apps or shortcuts.
