Dual window anyone?

Man it's getting so annoying looking at ove4 10 icon packs in my dual window list and I dug into one's manifest and found its just a few lines in the meta data that give the packs permission without root. I found a test apk on here where someone make an apk that opens perfectly in DW without root and apparently he disappeared on the project. But I'm thinking a kinda "adapter" app could easily be made to slip any other app into DW without rooting which sooo many owners would love considering almost every variant has an unsociable BL with no real recovery and only a very precise root requiring some skills or just balls to try. Or if there's a way to slip those lines of code into an apps manifest and it still function could work I guess too. Anyway if there's anyone with some Dev skills willing to look into this alot of g4 owners will be tickled I know I see so many people disappointed with only a handful of stock apps usable.
