3. Scaling upon export:

When exporting an image for display on the web, the image usually needs to
be resized, and sometimes you might want to make some additional edits at
the reduced size before the final export. But not always. It would be
convenient to have the option to scale the image as part of the file export
dialog, leaving the GIMP XCF file at the original size.

For current Gimp there is the "Save for Web" plug-in that lets you
crop/scale the image. However it's not uncommon to do a little bit of
sharpening after a downscale, or maybe add some watermark... Better take the
habit to use Image>Duplicate. This creates an "untitled" image to there is
little risk to overwrite the original image with a scaled down version(*).

(*) in the "belt-cum-suspenders" series, shouldn't Gimp issue a warning when
saving an image if it detects that the image has been scaled down/cropped?
This is another case of potential accidental loss of data. **ducks for

IMO, the medium term solution for all export-workflow problems is to have
an in-gimp way to manipulate a set of transformations to be applied to an image
on export.

Thinking on an UI for this now is up to us - so, why not bring the idea
to the list?

Currently, actually most export plug-ins do perform a
image-duplicate, image-flatten (or merge visible layers) and save
the resulting layer. Indexed formats do a "image-duplicate,
image-flatten, image-convert-to-indexed" sequence.

Having this in an UI would allow one to have several presets like:
image duplicate, image-resize(max-width: N, preserve-aspect: True),
image-sharpen, image-flatten, image-convert-to-precision(8bpp),
gimp-pause-for-review, export-to-desired-file-format  )

That would allow presets for example, that could at once save for the
various icon-sizes needed for
icons in mobile projects bound to a single keystroke. (and having  a
"mark as clean" node available for these presets
could also give an option to the "I do only jpeg exports" shouters)
