Describe the improvement

I liked the minimalistic interface of the app, but those new drawings that were added recently don't really add any value and they are a bit childish. Replacing them with minimalistic icons would be much better tbh.

Describe how this improvement could help users

It would make the app look more serious instead of being a child's toy.
