When I have looked for documents on LW, I have noticed that you will simply see all the results mixed together. Like ch1, ch2, ch3, ch4. And when you see things like that, you wonder: chapters of what? My solution is to allow the folders shared on the remote gnutella machine to be visible in the results.

A thumbnail feature should also be incorporated for easy perusal of picture searching.

As for text files and PDF's, a feature that allows you to see the first few sentences of the content when you move your mouse over the result would be nice too.

These are very good ideas, Johan. We will think about how to add this for future versions.

Shareaza has already some kind of protocol extension for previews...

Since gnutella uses HTTP.... Perhaps when an HTML download is requested, a default browser could be fired up and pointed to that machine.
