Mylyn Task Focus UI

You can uncheck "Window -> Preferences -> Mylyn -> Context -> Auto expand tree views when focused", this may help to some extend.

I don't generally need the structure inside the Java file, so I just disable that in the Package Explorer completely. To do that:

• go to the View menu (the little triangle)
• choose "Filters"
• check "Java Members"

Unfortunately, this doesn't work in Project Explorer.
