Re: [PATCH] Add directory diff options for shallow file comparison mode

[Claudio Fischer <claudio fischer freenet de>]

I also want to have this options in meld for directory comparison.
We are working with a similar tool for windows called "Compare It" and 
"Synchronize It".
The directory comparison shows file date / time and size in the tree 
view. This is very helpful.
See pic here:

Claudio
