Create an action where when clicked a much larger text box pops up next to the step to give a detailed explanation on the step to be performed.

Currently the 8 line limit can sometimes be too short to fill in what to do and you can't always split a step up into 2 to accommodated for extra details, also this runs the risk of missing out on vital information.

Also having this can be a way to explain why the step is important and how it can go wrong, if extra media could be added to this to show what happens when this step goes wrong would be even better.
