I'm on Mountain Lion with Proclaim 1.6 (latest version at the time I'm writing), and I think I've hit a bug, but not sure if I'm doing something wrong.
When importing a Bible reference, I've set the option to "Show reference at end", however this doesn't affect the placement of the reference at all. It still shows at the beginning. If I manually move the reference it gives me multiple Signals, as it thinks there are different references that it should be pushing out.
