Hello, nice idea

There is a message that i can't read because it doesn't as long as i can read it.
Could you add an option for timer for this message ?

What message do you mean? Please format your issue in a clearer way

I play with a modded version
Sometimes i wake up in night with a message saying there is some noises, but it's timing is too fast for read it easily

These are hotbar messages added by vanilla, so I can't really change their duration, sorry. If you're having trouble reading the whole message, you can take a look at all possible messages in the translation file.
