Support messages too long for the notification.

Hi,

I love your project! It looks amazing and clean and easy to use! I noticed that if the messages are too long for the notification, it just runs off the end without any indication that the message continues. I made a small change where the font shrinks by up to 25% to accommodate slightly longer messages, and clearly shows the "..." at the end of a message which is too long. I hope this is helpful for you. Thank you for making this!
