[Evolution-hackers] 'vertical' view?

[gabor <gabor z10n net>]

hi,

how hard would it be to implement a 'vertical' mail view...
like you can find in mozilla-thunderbird, pan or in outlook.

or simply see this screenshot from pan (news reader):

i think you all know the reason for thi feature:
the mails you usually get are longer than wide.

i don't know anything about the evolution source code.
1.how hard would it be to implement this?
2.if for example i implement it, could this feature be added to
evolution?

thanks,
gabor
