Welcome to InkscapeForum!
Yes, this is more of a users' forum, than a developers' forum. Launchpad is indeed the best place to request new features. And I don't mind creating a new feature request "bug report". But I'm not sure it's an appropriate request (explanation below).
First, I'm not sure what I'm thinking about this is correct. But I'll just put it out there, and others who know more about it can comment as well.
Oh, well before I offer my probably less than helpful comments, I might refer you to this page
http://wiki.inkscape.org/wiki/index.php ... Repository which contains many more extension than what ship with the program. Maybe there will be one that will help? Also I'll mention the info in the manual, just fyi
http://tavmjong.free.fr/INKSCAPE/MANUAL ... -SplitText.
Since I'm not familiar with that exension, I've done a bit of experimenting. First I created some random text using the Lorem Ipsum extension (3 paragraphs, 4 sentences each) and then ran the Split Text extension. I was a little surprised to learn what it actually does. But it's certainly not the first time I've been mislead by some of the terminology used in Inkscape. (E.g. Fractalize extension has nothing to do with fractals! And many more examples

) But I do get the idea....sort of.
The first thing I learned, is that each lorem ipsum "paragraph" is considered a line -- a line of 4 sentences, as far as the Split Text extension is concerned. So what I think is that Inkscape has no particular idea what a paragraph is, or maybe a sentence either. I'm not sure how the Split Text extension even recognizes a line. If I just type a bunch of text, and don't use lorem ipsum, a line appears to consist of everything between Enter/Returns.
So my guess is that Inkscape would need to have some definition of a paragraph, or any new extension would have to somehow be able to determine what is a paragraph. Maybe it could be as simple as a double Enter/Return, but that might not work in all cases. But how to make this work is WAY beyond my understanding. I'm just saying that recognizing paragraphs in order to "split" them might not be consistent with SVG or XML standards. Maybe it is, and if it's reasonable in those terms, I'd be glad to put up a request. However, if someone asks for any clarification, I wouldn't know what to say. You might end up having to register there anyway, to potentially provide certain details.
Or maybe someone else would have a better understanding, and wouldn't mind making the request?
