Here are a few other examples:

With 'tclvfs', one can easily create a listing in Tcl of remote
resources of all sorts of kinds (webdav, contents of zip, ftp, etc).
One wants to be able to drag those out of Tcl into the native
filesystem, and not just on Windows.

With an image browser, one would want to be able to drag a thumbnail of
an image which refers to a multi-megabyte RAW image on disk (which
would be what is actually dropped on success.

With a database browser, again one wants to be able to drag things out
into the filesystem, with the actual database query on happening on
drop success.

etc.

In all of the above cases it would be helpful to see a progress bar as
part of the successful drop, just as you would typically see with a
non-Tk application which implemented the above kinds of operations.

cheers,

Vince.
