the problem with using only one window is that I cannot do automatic 
dragging, copy and paste, etc in a single windows using apple's API 
from MLTE. It will be a lot of code to be written because in MLTE all 
the text in a widget has the same read/write priviledges. It is 
something I don't think I'll do in the near future as it has low 
priority in my opinion. I think that the primary goal is to release a 
functional Aqua GUI for the Darwin build without essential limitations: 
which means that I have to fix the problem with tcltk, we should 
provided an automatic way of distributing prebuilt versions of the 
packages and fix several problems with packages (tkrplot doens't work! 
uuid (for BioC) etc). This would be done before october. There are also 
problem with grid/lattice and quartz I have not yet fixed. The 
eventloop issue is another delicate problem.
It is in my mid-term plan to fix this problem with separate 
input/output (and of course any contribution -i.e. working code- is 
welcome), add a toolbar to the console window, etc, make RAqua 
applescriptable, etc.
