Highlight sentence rather than paragraph?

I love using Limelight and Goyo for writing text, after initially discovering it through seeing iA Writer. In a recent look, though, I noticed that iA Writer seems to highlight each sentence rather than each paragraph. I haven't used it, but it seems intuitively more appealing to me.

Would it be possible for Limelight to highlight just the current sentence rather than the current paragraph?

No file, test, or entry point is named in the issue. Start by locating the existing paragraph-highlighting behavior in the Limelight plugin, then determine how the current sentence can be identified; done means Limelight highlights only the sentence containing the cursor rather than the whole paragraph.
