One way that Yahoo could make the Mail surpass anything else is through
the ability for the user to completely customize the interface. I'm
thinking like basic options for command keys, where the folders section
is, message panes, buttons placement, skins, incorporation of hack
apps, etc. Each user's settings could be changed through a drag-and-
drop WYSIWYG template. There could be a couple official templates to
chose from, or people could customize theirs. If it can be done with
Flickr and Facebook, why not Mail?
On a side note, what does anyone know about the possiblity of a stored
files folder, with a disk image program for the desktop for syncing?
That would be serious functionality.
