I would like to be able to rename bookmarks in the file chooser.

I often bookmark directories whose names by themselves are not very expressive,
so I want a different name for those directories in the bookmarks list.

Example:

  directory ~/projects/foo/src

will show up in the bookmark list as 'src' when bookmarked, whereas I'd like it
to be 'Foo' or 'Foo source' or something similar.

Another example:

  ~/Documents and /media/workgroup/common/Documents

Cheers
