Good one handed mode?

[Soundtallica]

Does anybody know of a good one handed mode that can be used on the 6P? I'm rooted, have Xposed installed, and generally willing to do anything, even complicated software stuff for this. I'm currently making do with the Niwatori One-Handed mode Xposed module and Chrooma Keyboard's one handed keyboard, but I'm looking for something more polished.

If there's such a thing, let me know here! Thanks!
