UIInput

Just as a curiosity. Why do you have a public remove focus, but not a public focus?

The description above the function explains:

1.         /// <summary>
2.         /// Convenience function to be used as a callback that will clear the input field's focus.
3.         /// </summary>

It's meant to be called from some delegate set in Inspector.

When using code, use UIInput.isSelected.
