"- I wonder how to get back to Nautilus. It would be nice to be able to use both."
thats an annoyance for me too, I would like to be given the option to choose what browser I want to use depending on the situation. Also your comment on the comments is a valid one, I think we need a more dynamic browser in general which currently Pharo lacks, that does not try to choose for us how to do coding and instead gives us the choices . Of course dynamic browsers are more effort.
