Door Variants or Door Customization

Doors choices are limited despite having one for each wood type. The types with windows you can’t really put as a “bedroom” door, and I would really like to have a window door as the front door that doesn’t bash my color palette.
.Enter: Door Variants.

• To add them in the simplest way, just have each wood type have a window and a windowless variant.
• To add them in the best, but most complex way, create a customization mechanic similar to either the banner system or the armor trim system where you start with a windowless base for each door and are able to put a custom window into the base. This would be ideal (in my opinion) as it would be a small revolution in Minecraft building and customization. (As well as quality of life).
