I have no more info than you do but here's hoping! 
There's this, which I see you've already found. I wonder if @peternlewis has any plans for any UI element retrieval tools within KM itself, now that UI Browser is on its way out to pasture...? I'm sure people would love that and it would open up a lot of possibilities, but I also have no idea how difficult it would be to incorporate, so forgive me for @ing you, Peter!
