What are you missing in ET?

We just posted the new version of ET (r1600) on the website. It is the one that we used during the ET Training Day in Vienna on Oct. 22nd. 2010. We are continuing to fix bugs but this version is already fairly stable.

We would like to hear from your experiences, for instance, what features are you missing, are the documentations sufficient for you to use ET for your research, where are you struggling with it?
