I might have overlooked something, but what's the difference to the
already existing Image-Map filter (see Filters/Web/Image-Map) and Slice
The first filter already has possibilities to make rectangular, circular
or polygonal selections plus options for the URL or frame to jump to and
The map itself can be saved, too.
Wouldn't that be a duplication of functionality? If not, maybe these
already existing possibilities build a foundation for the "new slicing
tool" and can partially be reused?
