identation on eclipse scala editor too strict

Hello,
I have installed the Scala plugin for Eclipse (3.4.1) available at
http://www.scala-lang.org/scala-eclipse-plugin.
It seems that the editor for Scala source code forces identation too
strictly.
For example, I press TAB and the closing brace will not reposition itself.
Is there a way to relax this behaviour? I have found no preference switch
on the plugin interface regarding this.
Scala is amazing.
Cheers.
