I personally believe that little things make a difference. Eclipse 3.6 is going to be great for new (and perhaps also for experienced) plugin and RCP developers.
Especially I like in the Eclipse 3.6M4 release:
-consoleLog included per default in a new launch configuration
RCP with a View
I believe the solution of Bug for -consoleLog will solve the most common problem with getting started for new Plugin / RCP developers. Also the update of the PDE RCP templates will hopefully guide new developers in using commands instead of actions.
The change in Bug for -consoleLog was also a community decision, which is a good example that Eclipse does consider user feedback.
Thanks to all involved parties and the Eclipse community for these changes. 
Update Unfortunately Mail Template was not part of M4.
