This patch still applies well and works as intended.

There is one UI suggestion inline.

I think it might make a bit more sense to move this into the
advancedColumn1 as well, as now it is displayed in the opposite column,
which makes the UI flow kind of confusing.
Perhaps an even better option though, would be to move the displayfield
into an advancedColumnB, which would also remove the line width limit
and with it the somewhat ugly line break.
