suggestion - group same-size results

I have a suggestion to improve the search results:
- have an option to extend the grouping feature so that any returns with the same size will be considered the same file

This will necessitate some system of ignoring the differing filenames that currently prevent them from being grouped together, and also to allow you to half-download the file under one name, then continue retrieving it from someone else who has the same-size file but with a slightly different name.
