Flow Navigation is an add-on that replaces Blender's default 3D viewport navigation. It introduces a physics-based scrolling system for smoother zooming with inertia, alongside an adaptive speed mechanic that adjusts to the scale of the scene. The add-on includes an automated clipping system to prevent geometry intersection and an auto-focus feature that centers the view during zoom operations without requiring manual panning. A smart target search function identifies rotation anchors even when the cursor is not directly over a mesh. The add-on also provides a modal interaction mode that allows users to control zoom, orbit, roll, and pan simultaneously using mouse movements and clicks. Additional features include quick snapping to surface normals, a radial menu for orthographic view switching, and a dedicated in-viewport interface for adjusting settings.
