Feature requests: favorites

[noirbizarre]

Hi 👋🏼

Recently used emojis are very useful, but there are some times when I need to use less common emojis for stuff like documentation. When I do, they move into recently used emojis as expected, but this made me realized that more than recently used emojis, I need favorites because there are some emojis I really often use, and I love having them directly on the widget without the need to search.

This should not replace recently used, because when I use less common emojis, most of the time I need them multiple times. I think both features are complementary and cover different use cases.
