Buttons sprites auto-adjust to match

[Nubeh]

There's something a bit annoying about NGUI buttons: if you move the anchor of a button or switch between iOS to Android build all the buttons colliders position gets ruined. Of course I can select each button one by one and chose NGUI -> Add Collider to reset the position, but it gets tedious when my scene has 30-50 buttons.

I noticed that the new NGUI 3.0.3 has an 'auto-adjust to match' option on sprites...but in case of buttons I don't need the background to have a collider, I need the Button object to have one in order to listen for onPress events.

Is there a way to having the colliders resizing and repositioning themselves on button objects automatically?

Pivot change I can understand, but what does switching to a mobile platform have to do with it? Collider sizes don't get updated unless you make them get updated either via the option on the widgets, or by doing so yourself.
