It worked, thank you Nathaniel!
I’m impressed by how quick you answered!
Using this new labeling tool does indeed solve basically the problem!
I would like to prevent the names on some islands to appear (some instance Jersey). Using the old labeling tool, I could filter with SCALERANK to do that, but I don’t see how to filter the output of the new labeling tool. Can we apply filters to it?
As a workaround, I tried defining a new field “LABEL_SIZE” (=13 is scalerank=1 and 0 otherwise), but I didn’t manage to set the label font size to the value of this field, because this new field did not appear in the menu proposed in the label properties window. If you have any tip, I’ll appreciate!
