As you probably noticed, attachments are stripped from list mail. It's
much better to post the image any of the free services out there, and include a
link to it.

Filters sound like the right approach. They're for when you don't
want/need to constantly requery the database.

Not initially, but you're going to have to when you want data to be
displayed.

Yes, but only for text and files. Dragging from controls requires the
developer to handle the mouse events manually at the wxPython layer, and from
experience, this is not very easy to do well.
A better interface might be something like the 'mover' class included
in the 'ide' directory. That uses a pair of lists, with buttons to move items
between the lists.
