Generic/Custom Showkase Annotation

[eddnav]

Why can't we have a single annotation like Showkase for all the UI elements? Why did you create a different annotation for each UI element(@ShowkaseComposable for composables, @ShowkaseColor for colors & @ShowkaseTypography for text styles)?
This was done mostly for future proofing. Even though these annotations have the same properties right now, it's possible that they will diverge as we add more features. Once more people start using this library, we will get a more clear idea about whether that needs to happen or not. If we find that it didn't evolve the way we expected, we will consider consildating these annotations.

I understand the decision behind specific annotations for each type, but it would be nice to also have a custom (can behave just like @ShowkaseComposable, just not grouped under "Components") annotation to allow more flexibility. An example of this is shadows. My design system has custom drop shadows, not elevation and I would like to display them in Showkase.
