More information in File Open/Close Dialog

[Marko Randjelovic <marel ni sbb co yu>]

When you click on "Browse for other folders", you get a list of files 
with only their modification times. Don't you think it's too poor 
information? It would be very useful if one could turn on displaying of 
other information, such as file size, owner and permissions.

I would like to hear other opinions about this, and also developers 
about would it be difficult to implement.
