when compiling, I get this warning about a missing header:
cc DrawView+Drawing.m -c \
      -MMD -MP -I/usr/local/include -DGNUSTEP -DGNUSTEP_BASE_LIBRARY=1 
-DGNU_GUI_LIBRARY=1 -DGNU_RUNTIME=1 -DGNUSTEP_BASE_LIBRARY=1 -fno-stric

       -o obj/SpaceTimeViewer.obj/DrawView+Drawing.m.o
DrawView+Drawing.m:26:20: warning: values.h: No such file or directory

which, IIRC may lead to an error when compiled with clang, or newer gcc.

Otherwise I get some warnings regarding incompatible pointer types of 
arguments, which may, as far as I know, lead to weird errors on some "not so 
common" platforms.

If you are interested, I can send you the whole build output.

At a first glance it seemed, there are two separate boxes for the Thread Data 
and Monitor Events, but they seem to be on top of each other. I managed to 
change the sizes, but the Monitor Events always seems to align to the bottom, 
and there the Thread Data is written on top of it (or behind). See new 
screenshot.

Ah, OK, then good to know that its not just me ;)

Yes, that would be indeed great I think.
