N-Panel Manager is a workspace organization tool for Blender that allows users to manage and group addon panels within the 3D viewport's sidebar. It features a quick tab switching system to organize addons into project-specific groups, helping to reduce interface clutter. Users can select and activate multiple addons simultaneously within a single custom tab to create specific workspaces. Additionally, an exclusion feature allows specific addons to remain in the main N-panel area while others are filed into managed folders.
