Much better UX!
- Interactive elements are shown clearly and the cursor changes based on context:
Customizable visual handles for anchor and joint limit configuration
- Check out the data/settings asset for visual and other configuration :D
Context menu on anchors, just right-click the anchor or the limit handles!
Anchor locking e.g. when you move an anchor, the other one moves with it
- Hold shift and click on any anchor to toggle locking
Drag any object reference onto the main/connected anchor handles, and it will auto-magically be connected, as long as it has a RigidBody2D component
Hold control while dragging the handles, this allows you to snap the anchors and limits
- The snapping positions are highlighted by circles
Can see transparent outlines of all joints connected to the selected object
- Configurable via Settings -> Connected Joints
Hinge Joint 2D:
- Object movement circles:
- Better limits display (can click and drag the lower/upper limit indicators):
- Hold control to snap to nice angles!
Slider / Wheel Joint 2D:
- Configure and see angle visually
Slider Joint 2D:

Spring / Distance Joint 2D:

You can now download through the Asset Store.
Otherwise, just add the .unitypackage file from the release to your project ( double-clicking the file should do it automatically )
Select any object with 2D joints, you will see that the scene view will now show the updated UI
You can configure each joint's extra features in the inspector
You can also tweak parameters in the 2DJointEditors/Data/settings asset!
