I would like, don't know if more people would like too, to have more flexbox properties, right now is missing one big property that is justify-content by space, evenly or around.
This way, we would stop manually create divs inside divs and putting columns just to align one div to the start and the other to the end... Is almost wrong in my perspective, and would be easier if we had a justify-content: space between(or around or evenly) to help us align our structure.
1-examples of what we could have on SS aligning our div parents

We could have also a parameter saying what kind of alignment we want to that div

Let me know what you think. Thank you
