*2023-09-21*

日历上有颜色区分就好了。
当天记录的重要信息后，在日历上并没有颜色区分，于其它未记录的日期颜色一样。颜色相同不方便查找。
只能在另一页全部事件中翻看

### 4/5 — Good but Widget needs some work

*2022-12-21*

I love how everything in this app feels, unfortunately, the widget can only show the pre-made “New Years” event. For example, I have a “Christmas” event in the app, but after going to edit the widget, the only event showing is the “New Years” event. If this gets fixed, I will edit this review to accommodate that change.

**Developer response:** Thank you for your support and suggestion!

Currently the widget only supports displaying D-day Event(event without a selected repeat type).
I will be adding more display options soon to support showing all types of events in the widget.
