Here is a mod that allows you to have windows that are not in the center of the blocks, you can also place them horizontally! What standard windows don't do.

Although it's only a small modification it changes a lot of things. With them you can make beautiful interior and exterior decorations.

For example, they can be used to make railings, fences, aquariums or fireplaces, and even glass ceilings and floors!
In addition, all standard glass colours are available!

Have fun!
