Suggestion: Allow exporting part of a document in vector formats
Inkscape can export any part of a document (selection, page, etc.) as PNG. However, it's not possible to do the same with other formats. It would be very useful to also be able to export a part of the document as SVG or PDF.
Example Use Case
I'm working on a set of icons for my website. It's important to be able to see them next to each other and quickly iterate on all of them, so I'm drawing them all in the same file, next to each other. Once I want to use them on the website, I need them as separate SVG files though. The only way to do that currently is to manually copy each of them to a new document, resize the document, and save them as plain SVG (which is of course very tedious and time consuming).
Potential solutions
One relatively simple solution would be adding a file format dropdown to the export dialog, where one could choose PNG, SVG, PDF, etc.
