>>2059438>>2059279 and >>2059288 are both meI personally don't have a navbar in my OS at all. I replaced it with 'All in One Gestures' and remapping the bixby button with 'bxactions' for navigation. It's much faster and easier for me. That's a preference though, so if you're happy with the nav bar you can keep it (remember that nova only disables it on the homescreen AFAIK)
To remove the clock just search up 'remove lockscreen clock xda apk (your phone name)' and look for a an apk on the xda site. If you go to settings in klwp and click set as wallpaper you'll get an option to set klwp and both your home and lock screen wallpaper.
As for the animation stuff I'm a little confused in what you want, but I'll try and help anyway.
Make a 2 global switches as on/off and enable only one of them. Then find the images you want and assign their touch settings to one of the global switches each. Then create animations on both images to react on the global switch assigned as their touch command and set them both to fade out.
If your animation doesn't move far enough when you scroll just increase the speed of the animation. I have it at 300 speed because I have 4 pages. You might want to use something around 250. Make sure everything else has the same speed or icons will start going in front of each other.
I love the theme you have now, it looks absolutely awesome and the colour palette is so unique. You have really good taste, it's also one of the rare instances that such a tacky font looks really good.
Congrats.
Here's an ugly half arsed combination of my theme in one image. I don't like it anymore so I might start again from scratch.
