Avoid big multiline titles

Hi,

I think is not the best approach to solve the problem, but basically, would be awesome find a way to let's the user customize:

- Title
- Body
- Stacktrace

I didn't had the time to come up with a clever solution but at least this seems to solve some problems where the  `error.Error()` is quite big.

To give you some context basically my apps generally have one file main/manager that handle errors/logs etc...
