I really like the new UX, very clear and responsive

However,
1- One feature I found missing and was a time-saver is to apply a setting through all apps. I had 4 apps setup, and I decided to change a custom button config. Instead of just clicking once, I had to replicate the customization in every single app.

2- Backups! I used backups as a away of syncing between different devices. I am not sure how to sync now.
