Blender Actions is a new pack from Unity Asset Store that features a set of commands for Unity Editor.
The Hotkey-Based Gizmo allows you to save time when building your levels as you no longer have to hunt for the miniature Unity gizmo UI and no longer need to fear misclicks. Moreover, features like Custom 3D Cursor, that can be used as a pivot for rotation and scaling of objects as well as Vertex Snapping for translation rotation AND scale can increase your overall level-building productivity up to 3 times. The gizmo also works when editing colliders, which turns a chore of working with default collider editing UI into a breeze. Check the documentation for detailed info.
