for changes to More, please use github pull requests. You'll want to issue that request against the 1.2x branch. Also if there are spaces here instead of tabs, you'll be shot down.
I don't think this works. It means that if you set your tips value to "alt" and there isn't an alt your title will be "alt". For your use case, just set the option to be a function if you want it to do something different.
I don't think you need this either. I'd rather you do: if (!this.tip.parentNode || document.body.hasChild(this.tip))
seems like maybe other changes in the class would make this work better. in the elementEnter class you could define this._titleElement or something and skip running this selector.
