I think that sums up pretty much everythingWhile I have already answered these questions there is actually more to say to the topic of what hearts are capable of and how they influence people that I haven't brought up yet, so I feel like as if it would be appropriate to do so now for the purposes of this thread.
- Hearts cannot be contained by data and the process of digitalizing them is incalculable. A machine designed to digitalize an artificial Kingdom Hearts failed and exploded.
- Digital beings can have hearts despite hearts being uncontainable for data. A digital being gained a real Keyblade in place of an inferior imitation it previously had signifying that it had a real heart and it was said that it had surpassed the system because of that.
- It's impossible to recreate a heart based on data and a process like that can only achieve a partial restoration.
- When Xehanort's heart possessed Terra Terra's previously brown hair turned white and his eye color changed to yellow both of which come from the white-haired and yellow-eyed Xehanort. Later in the series people who carry a fragment of Xehanort's heart are shown to have yellow eyes.
- Vanitas, the person whose heart only contains darkness, took on a similar appearance to Sora the moment Ventus, Vanitas' other half that only has light, came in contact with Sora's heart.
- Memories are a key element of the heart and if they are lost, forgotten or altered, then that can result in things like the heart collapsing or reality being rewritten. Memories can however never truly fade and the heart can recognize things that the mind doesn't.
- Sora was able to make an alternate version of a friend he previously met remember him even though he had never met that alternate version before.
- Nomura contemplated the depiction of Sora's heart existing before his birth but discarded the idea due to beliefs from overseas that the heart doesn't exist until after birth.
- Xehanort's heart was merged with another person's and he received glimpses and dreams of that person's life as a result. Sora had the hearts of other people contained in his own that caused to feel a sense of familiarity with people he didn't actually know and even had hallucinations of people that those other hearts knew.
- Disembodied hearts can completely reconstruct their bodies provided there is a medium and a person who remembers them.
- If a Heartless and Nobody, which correspond to the same person that succumbed to darkness and subsequently created them in the process, are destroyed, then that person can come back completely.
- Hearts can form connections which can allow for telepathic communication under certain circumstances and can be used by those who mastered the Keyblade as a method of travelling through space and time.
- Xehanort stated that people who had hearts came from the light that arose from the darkness in which the World, basically the entire setting, began and that the first light is Kingdom Hearts.
