sorting lists by multiple criteria

[anonymous]

As the summary of the ticket suggests, sometimes I want to sort lists by multiple criteria, e.g. sort search results e.g. like this:
by user
files by the same user: by folder
files in the same folder: by filename

A logical way to achieve this would be to:
sort by filename
then sort by folder
then sort by user
(sorting works like this at least in some programs, that's why it seems logical for me)

Alas, Nicotine+ currently (i.e. in version 1.2.9) only supports sorting by a single criterion. Can this be improved, please?

Here's an idea of how to sort items: Starting from left, sort things by the first column. If it contains multiple identical entries, sort those by the next column and enable a collapse button, effectively creating a nice, powerful and intuitive tree view.
