I've already almost finished the work. Unfortunately, a problem(*1) 
caused the work to stop for a few weeks, but the problem has been 
resolved(*2), so I can continue working. I'll post a patch soon once 
some minor tweaking and testing is complete.

By the way, at some point I switched from "continuing your work" to 
"recreating a new one based on my current work." The results of my 
current work(*3) have changed significantly.
