Ted,
Thanks for implementing the export hints. There are a number of problems that I found in testing them today:
1 Why "Custom" is the default? As before, when I open Export, it must switch to Selection if there's selection, otherwise to Drawing if there's a drawing, otherwise to page. Switching to Custom must be possible either manually, or automatically when you change any of the x, y, w, h parameters (i.e. when they no longer correspond to selection, drawing, or page).
2 The dialog does not track selection change. It did before. Now it must not only change x/y/w/h when selection is changed or modified (as before) but also reread the filename and resolution hints when the selection is changed.
3 When I do export and the hints are remembered, the document is not considered changed. So I cannot save it (unless I change something else) and the hints are lost on close.
4. When there's no filename hint and the export filename is constructed from the document filename, it does not remove .svg which results e.g. in "wa.svg.png". This did not happen before.
Please fix these problems and we'll have another killer feature for this release! I'm very excited about it.
