短信受地心引力作用

????短信現在適用萬有引力定律，至少是蘋果版本的萬有引力定律。泡泡狀的短信文本都有一定的虛擬重量，當用戶在不同的短信中滾動時，這些泡泡會分離開來。而當用戶停止滾動，短信消息再次合在一起。這不是什么重大改進，但用著很順手。

Messages subject to gravity

????Messages are now subject to the laws of gravity -- or at least Apple's version. Text bubbles have been assigned their own sort of virtual weight, so when users scroll through them, they pull apart. When users stop scrolling, messages merge closer together again. Minor, but neat.
