One could run the notebook from any directory ever since the

That's the design. If you type
"sage -notebook"
or type the notebook command but don't give a directory name,
then the default notebook sage_notebook in the current directory
is created and run. The same is true for the wiki (e.g., type wiki() to
run a wiki from the current directory).

How do you start the notebook? Do you type "notebook()" from in SAGE
or do you type "sage -notebook" on the command line? If you start the notebook
from the command line, you might just create a little shell script that cd's
to SAGE_ROOT and then runs "sage -notebook":
cd /home/dfdeshom/custom/sage/
./sage -notebook

The mode thing has been in SAGE since when the notebook was introduced.
But the interface to use it is sucks, as you've discovered. I'm
amazed I haven't
improved it yet, but I've been so busy with other things.

At some point you must have typed notebook(system="gap") which sets
that copy of the notebook to create GAP worksheets by default. You can
also do notebook(system="maple") so that SAGE will create only maple
worksheets by default. Existing worksheets in the notebook aren't affected --
just new ones use the given system (and always will in the future). This
is actually a pretty cool feature; my impression is that a lot of people use
SAGE mainly for this feature.

Just try notebook(system="maple"). Actually anyone can easily make modes
for anything -- if you start sage after typing notebook(system="foo"), then
all input cells get passed to foo.eval(...) and the result gets
displayed. That's
it. So if you add a foo object with an eval method, you get the option of
a foo mode. E.g., Bobby Moretti easily made a jsmath mode this way; in fact,
just try notebook(system="jsmath") to get jsmath notebooks. You can always
go from one mode to another in a given worksheet by putting %modename
at the top.
