Custom date picker for properties

Use case or problem

When selecting a date in a note’s properties, a date picker appears. The current on seems to be inherited from Chrome, which means it does not fit with the rest of the interface (similar to the old PDF viewer). I don’t think it can be modified using CSS snippets, but I could be wrong.

Proposed solution

A custom date picker that fits with Obsidian’s design and is customizable using CSS.
