Is there a complete list of features that have been removed in subsequent games? If not, I want to compile one, but my knowledge is not comprehensive enough, so I'm asking for help.

Including things that were "replaced", like Horde Battle -> SOS Battle. Including things that were removed and then added back again later on, like Battle Frontier (absent from DP), or O-Power (absent from SM). Including small things like menu shortcuts and QoL changes. In spite of my O-Power example, let's avoid USUM because we don't know what it will have yet.

Basically, list every cut (temporary or otherwise) feature you can think of, from any generation or game. Or if this list already exists, direct me to it?
