Dark Mode is 1:1 dark mode from Mate 10 Pro, and Dark Mode Pro is an extended version: different icons, toolbars, only blue accents (no green).
I can send you a themed wahtsapp, but the only what I can not change is the Ballon for outgoing messages. But I have also a other themed WhatsApp (not from me) where it is changed.
And I have found two bugs. When I want log me in in games or apps, I can not see what I wrote, because the font color is to bright. The Screenshot is taken while I want login in the Simpsons Springfield Tapped Out game.
And in the email app and Settings app, the bar on the bottom is jerking and twitching sometimes.
