Comment 2 for bug 1515504

Hello Mark,
If I understand your problem correctly I don't think what you are seeing is a fault with hugin-2015.0.0.
This version only shows the Optimiser and Exposure tabs when these optimisations have been set to use "Custom settings", which you should see in the Photos tab using the Advanced or Expert interface.
Have a look at the Hugin Tutorials <http://hugin.sourceforge.net/tutorials/index.shtml> particularly "The new user interface (2013)" shows what you are seeing.
