I would like it if multiline passwords would be
supported (e.g. to store keys).
It seems that the format already supports multiline
which means this could be done just by changing the
entry-field in the GUI. Maybe changeable by an option
in the preferences, so someone could use the easier
one-line-thing if he had no use for multiline
passwords. Or maybe directly with an checkbox next to
the entry-field which then changes the
one-line-entry-field on-the-fly to a multiline-text-ctrl.
