No, that’s the right place, I just didn’t look closely enough at the Twitter API there. There needs to be a separate url query parameter for the username, called via
. (the code at 593 is getting the data for all of the platforms, then it’s formatted for each platform below)
I noticed that I can and should also include the title of the post in the tweet by default, and looking into it more, I think this makes sense to add to the plugin, with a field for the twitter username.
I’ve published the changes to the development version of QuickShare, if you have a chance to confirm that they work as intended that would be great (I plan to push the update on Monday)! Unfortunately Google+ doesn’t have a similar functionality available in their API (yet).

Also, sidenote, I noticed that you have arrows showing up over QuickShare on your site; you can fix that by pasting this into the custom css field in QuickShare settings (your theme’s doing something weird):
.quickshare-container ul li i {
background: transparent;
}
