I noticed that the Nothing OS 3.2 has improved the animations but it feels too bland. The animation is very linear. Adding curves (fast at first and then slowed down) will surely improve the animation.
And this is where the app suggestion comes in. I recommend creating an app like Goodlock (Samsung) which will enable us to customize almost everything, including, the animation curves like it offers in the app.
If the animation curves could be customized, that would be awesome. Also adding customisation for the lockscreen would be great. With depth effect and either more clock faces, or some clock faces which would be extremely customisable (height, font, color, effect, etc)
