The existing web frontends are rather clumsy and inconvenient to use.
Browsing the results of a list or search request is a good example. In
particular, when filling in (multi-)links from a search, this becomes
very evident, as the process involves clicking through a cascade of
popup windows and frames.

This could be improved with a few small additions:
The server could provide a json interface to search and query, which the
different template could then make use of with some jquery.
