Feature description

I would like to integrate VisualDiffer with my apps (SnailSVN & SnailGit), but I found that it does not work well.

It is annoying that one has to select the files again and again when invoking VisualDiffer via the visdiff command line helper.
It is a nightmare if there are many files in the same folder.

Since VisualDiffer already knows the files to compare, why not simply allow the user to select the parent folders instead.
VisualDiffer should save these folders to the trusted paths automatically, so that one does not need to select the folders again and again.

Lets say that I have 2 files to compare:
/the/path/to/my/project/file1
/the/path/to/temp/file2

Please consider allowing the user to select one of the following folders:
/the/path/to/my/project
/the/path/to/my
/the/path/to
/the/path
/the
/

For file2, the parent folders are as follows:
/the/path/to/temp
/the/path/to
/the/path
/the
/

Why is this useful?

This will improve the user experience.
