Hi, Mark has provided a handy UNSW thesis layout based on the amsbook for lyx ( http://www.threewordslong.com/blog/entry/63/A_LyX_Thesis_Layout_for_UNSW_T) and I found it pretty nice in general for what I need, saving a lot of hassle of creating all the required pages from scratch.
However, I would like to make a few changes and not very sure how I can do that without messing with the lengthy amsbook style. 1. Bigger fonts for all the chapter/section/subsection 2. Change the Chapter/Section to be Left aligned 3. A new line for subsubsection I have tried to change the class to book/memoir style and it looks obvious that the layout doesn't work because some of the preambles depend on amsbook stuff (my guess). Any idea would be much appreciated.
