Needs to be the same as padding to the side of the plasmoid to look write. /me is a pixel alignment extremist.
Also no padding above the line edit.
Does it need padding above? The ListView has clipping on - I wanted to give the impression that the text is scrolling 'under' the lineedit. And as for padding below, when the panel isn't at the bottom, there is padding. I wonder if putting extra padding will make it double up.
I'd say this doesn't apply anymore, does it? It looks fine to me...
