In the "automated placement settings" of the new labelling system, it seems* that at least for point layers, the "Number of candidates" setting is only applied in the main map canvas, not in composer maps.

I have tested with 1.8 and a version of master that is a couple of weeks old (45a933a). I can't test the latest master at the moment as I am kind of cut off from the world.

• If the option "show candidates" is enabled, then the main map canvas shows the number of candidates that is specified, but composer maps always show 8 candidates.

I'm setting the "priority" to low because I think the "automated placement settings" aren't really expected to be used by end users.

Note that there are some other issues with the "automated placement settings", for example

• If "show candidates" is enabled, then the candidates are shown in the composer, but are not printed. Is this a deliberate design decision?
• The labelling of the different search methods seems unclear:

Chain (fast)
Popmusic Tabu
Popmusic Chain
Popmusic Tabu Chain
FALP (fastest)

Is this an ordered list, so the "fast" chain method is really the slowest method? Or are the three Popmusic methods slower than it?

that at least for point layers,

I just tested with current master and it occurs with polygon layers to. I haven't bothered testing with polyline layers.
