It's the same dialog as far as I'm aware. It's just that we can't
support preview yet for some formats (ok, most).

Yes. But see below.

Correct. So as you say then we won't need that huge popup list of file
types any more on the save dialog where you choose the filename.

Yes I think that will be ok. So the type list in B will include only
"all files" and the type that the user chose to export in dialog A.

We don't have time to change much before the 0.7 release. I'm told by
Luke that adding the "export as vector" and "export as bitmap" menu
entries won't be straightforward, so that means that we can't change the
order in which dialogs are shown in time for 0.7. So for 0.7 users will
still choose filename and filetype in the first dialog that comes up and
then they'll see the export settings dialog come up with it's previews
Given how far the new preview capability is from being to a release
standard, I'm not sure we'll have time for any of the following
improvements before 0.7:-
- Allow IM types to be previewed (currently the preview area just shows
a "preview is not supported for this image format" message for these
- Allow the format to be changed in the export settings dialog
- Change the order of the export dialogs so users choose the format and
settings (dialog A) BEFORE they choose a filename (dialog B) instead of
after. As discussed above.
- Make dialog A sizer based so it can be resized and generally improve
If/when we do have time, these improvements should be actioned in the
order shown above.
