here is a relatively small issue for the discussion.
ROOT saves command history somewhere in a file, so commands from the
previous session are available with "up"arrow.
This very nice feature has howevere a caveat: if one runs 2 or more
ROOT sessions in parallel, commands from all of them end up in the same
place, so in the next session you non necessarily retrieve what you wanted to.
Wouldn't it be better if the command history were saved in a directory
where the session starts? - I guess this could make life somewhat more
convenient.
