Problem

The current date picker is frustrating to use because it requires too many taps to select a date from the past. It is difficult to jump back to previous months or years quickly. Additionally, the app lacks a time picker, which makes it hard to organize multiple entries written on the same day.

Solution

Improve the date picker by adding a month strip to easily choose months and change the year, matching the timeline calendar design. Include an optional time picker within the same interface to allow time selection.
