What is Princess Twilight Sparkle's role as Princess?

Hello everyone. I have a question that has been bugging me as of recent. What do you think is Princess Twilight's role?
We have the Princess/Alicorn of Day: Celestia.
We have the Princess/Alicorn of Night: Luna.
We have the Princess/Alicorn of love: Cadence/Mia Mora Cadenza
We also got the Queen of the Changlings Chrysalis, but that's beside the point. What I am wondering is what is Princess Twilight Sparkle the Princess/Alicorn of? I would like to hear what you think.

I've heard many say she's the Princess/Alicorn of Magic, but any of the Princesses could claim that title, especially Celestia, who taught her and provided her every spell she knows. Plus, wouldn't we need a Princess/Alicorn for all the Elements of Harmony? Magic is one of the Six Elements of Harmony, but I don't see the other five being alicornified any time soon. So what do you think she will gain the title of in coming seasons? Please leave a comment on what you think.

2088735 Friendship? That would make sense. I like your style of thinking.

The spoiler heavy 'review' on EQD has already soiled this. I'll give you a hint. It's been mentioned by at least one person in the comments for this blog already.

SPOILERS But it was confirmed at the end of the finale she will be the princess of friendship
