The Sidebar Resizer plugin enables users to customize the widths of the left and right sidebars in Obsidian with precision and flexibility. Users can programmatically adjust sidebar widths by increasing, decreasing, toggling, or evenly distributing them using commands. The widths can be set in pixels or percentages, and both sidebars can be expanded or collapsed as needed. The plugin also allows users to define standard widths for easy toggling. This tool is ideal for users who want greater control over their workspace layout and prefer a streamlined sidebar management experience.
