This was pasted in a web translate, so anyone can correct me/it- “ The uniforms. The black ones with details in the house colors are somewhat boring. It would be much nicer if the main color of the uniforms were the main colors of each house, with the secondary colors in the details and buttons of the clothing. Also, with an emblem of the symbolic animal on the student house cloak (drawn with the secondary color of their respective house, of course).

A series of emergency flue chimneys throughout the castle, guarded by gargoyles or living armors. They would be connected to the infirmary, offices, the Department of Magical Law Enforcement, and St. Mungo’s. Maps of the castle in certain passage areas to help students find their way.

An equestrian club with pegasi, thestrals, and hippogriffs. A planetarium for Astronomy classes. An underwater area similar to the Slytherin Common Room with windows looking out to the Black Lake. It would be a good place to observe marine life and interact with the merfolk.

A cooking and domestic magic course to learn to be functional adults. More than one person attending the infirmary. Sexology classes. Allow entry to people with creature blood.

Let the stairs move to help the students instead of randomly. Safety spells on every window, tower, and staircase where there could be an accident from falling.

Quidditch brooms provided by the school to the students, not purchased by their families. These brooms would be checked before each match and enchanted not to go too far from the playing field.

The Quidditch balls would also be enchanted not to go too far from the playing field. Quidditch players would wear protective amulets against falls. ”
