Sorting, moving, browsing

[Elbert]

Is there any way to sort the directory tree that you get
when you click on My Notebook?

When I move a section from one folder to another,
the .mht, .msg, etc files that I saved in the notebook
don't follow. Any fix for this?

ON always uses IE when I click on a URL link. Any way to
make it use the default browser instead?

Thanks,

Elbert
