Possibility to select multiple/all fields for export

[laksdjfaasdf]

When exporting data it should be possible to mark multiple fields with Ctrl and mouse click at once an after that click only once the "Add" button.

Another nice feature would be if there'd be a button to select all (!) fields for export. Now you have to expand the whole list on the left side with lots (!) of clicks.

and/or "select visible fields (tree/form)"

because some visible fields are reational fields - IMHO most users will not be able to select the correct fields

something like address_id.partner_id.name is to difficult.
