• Nicki's Depth Management system
  
• Improved Localization System
  
• How to make health bars
  
• Action Bar system
  
• Packed Font with Outline/Shadow
  
• Font using Alpha-tested magnification (Valve's approach)
  
• Atlas switching / DPI control
  
• Atlas switching
  
• NGUI & FingerGestures
  
• Sliced & tiled sprite
  
• Photoshop -> NGUI
  
• Scale UIRoot based on width as well as height
  
• HTML in NGUI
  
• Dynamic Font + Emoticons
  
• Easy Window transition functionality

If you want to dynamically alter a renderer's draw queue (Renderer or Particle System), you can use the following script:

1. using UnityEngine;
2.  
3. public class SetRenderQueue : MonoBehaviour
4. {
5.         public int renderQueue = 3000;
6.  
7.         Material mMat;
8.  
9.         void Start ()
10.         {
11.                 Renderer ren = renderer;
12.  
13.                 if (ren == null)
14.                 {
15.                         ParticleSystem sys = GetComponent<ParticleSystem>();
16.                         if (sys != null) ren = sys.renderer;
17.                 }
18.  
19.                 if (ren != null)
20.                 {
21.                         mMat = new Material(ren.sharedMaterial);
22.                         mMat.renderQueue = renderQueue;
23.                         ren.material = mMat;
24.                 }
25.         }
26.  
27.         void OnDestroy () { if (mMat != null) Destroy(mMat); }
28. }

I wrote this before. if anyone wants to place a SFX in front/back of a widget, it's very easy to do that at runtime;

RenderQueueModifier rqm = obj.AddComponent<RenderQueueModifier>();
rqm.m_target = whichWidget;
rqm.m_type = RenderType.FRONT;

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class RenderQueueModifier : MonoBehaviour
5. {
6.         public enum RenderType
7.         {
8.                 FRONT,
9.                 BACK
10.         }
11.  
12.         public UIWidget m_target = null;
13.         public RenderType m_type = RenderType.FRONT;
14.  
15.         Renderer[] _renderers;
16.         int _lastQueue = 0;
17.  
18.         void Start ()
19.         {
20.                 _renderers = GetComponentsInChildren<Renderer>();
21.         }
22.        
23.         void FixedUpdate() {
24.                 if( m_target == null || m_target.drawCall == null )
25.                         return;
26.                 int queue = m_target.drawCall.renderQueue;
27.                 queue += m_type == RenderType.FRONT ? 1 : -1;
28.                 if( _lastQueue != queue )
29.                 {
30.                         _lastQueue = queue;
31.  
32.                         foreach( Renderer r in _renderers )
33.                         {
34.                                 r.material.renderQueue = _lastQueue;
35.                         }
36.                 }
37.         }
38. }
