When enabling a text custom field (the free version only has 1) there is an option to “Trim when displaying”.

This is useful if you are allowing people to enter some text in a field e.g. “Why did you sign?”, but when displaying the signature list, it is just too long.

If you enable this option, instead it will display like this.

But wait…the full text shows when mousing over

How cool is that? This won’t work on a mobile device, so instead the whole field is displayed.
