The Hide Sidebars on Window Resize plugin provides a convenient solution for dynamically managing Obsidian's sidebars. It automatically hides the left and right sidebars when the window becomes narrower than a specified width and reveals them again when the window is resized to a wider format. Users can customize the minimum width thresholds for both sidebars, allowing for flexible adjustments based on their workflow. This plugin enhances the workspace by optimizing screen real estate, making it especially useful for smaller screens or multitasking environments.
