Just to add to this.

1) The active threads, have each the same size
- minimum header + 1 line (maybe configurable),
- optional max height / if the window shows more, it can show the normal 
scrolling
  if it is does not fit into the window then some of it is not shown / 
can be seen scrolling (scrolling works well because they do not change size

2) a package in an active thread has 2 headers
a- the limited height from (1)
b- the full size, all unfiltered msgs (that is what is scrolled out)

a belongs to the thread, and changes from one package to another
b belongs to a package

3) If during compilation a code tool error happens (user does editor 
actions), it can be shown below the threads, and will not scroll away.
Makes sense, as it is a response to a user actions that was triggered 
after the start of compilation.

4) Option: the header can be folded to just a vertical line. for people 
who do not want it.
The window then simply is divided into un-named sections.
