Custom Template Samples for Web UI?

[SoccerDad91016]

Are there any examples of custom templates for the server web display that a person could review for ideas?

In particular I wonder if there is a way to group books by series instead of the default detailed listing.

I also want to change the way the series_index is displayed. I was trying to get the index to display as a regular number with leading zeros instead of a roman numeral. However, the following gets interpreted as a literal string instead of the field value:
{series_index:0>3s}
