Currently there are problems in the export in SVG format, especially for use with LO Impress.
There are problems in the bug mentioned as Bug 61314. In one of your comments (5) there is a good idea and would be appropriate to report it as an improvement.
Just as in the export to PDF, it would be good to add a menu export to SVG format. It has great capabilities and options that can be exploited (especially in Impress).
One option is the way to export the presentation: current page, pages x ... y, all, "pages as layers", "grid pages" pages as individual files, and more.
the idea of using sozi to reuse the presentation is very good, imagine creating a photo albun with Impress, SVG export everything and create a new presentation effects sozi and hang it on our blog.
The idea can be applied to other image formats, but SVG can be extended especially for their special abilities.
Perhaps a series of dialogs like those displayed for File > Export... > File Type of "HTML Document"? Agreed and confirmed. Status set to NEW. Version set to Inherited From OOo as this feature has never existed.
Setting version back from "Inherited From OOo" to what it was prior (for bugs marked enhancement), for QA tracking purposes. My mistake. Apologies.
UX-team, please look at it
I wouldn't expose the SVG on the menu root like PDF. It's just another file type and if we show this one could easily ask for compatibility and want pptx there.
However, when this is about a properties dialog that shows up after SVG was selected for saving, a dialog similar to print or PDF, it sounds reasonable. The dialog could take the sections Range and Images from the PDF options for now.
