In the thread view, the values will still be visible when the thread
goes to Warming or Cooling states, instead of being removed like when
the thread enters the Paused state. The CPU view will continue to track
the running thread (only in the Running state).
In Mac OS, the top menu bar is placed above any window, causing the
timelines being opened at (0,0) appear under it in such a way that the
timeline title bar is not reachable by the mouse, making it hard to
move.
This simple solution opens the windows a bit away from the top left
corner, at (100,100).
