Slide Layer vs New Slide
I am new to building courses with Storyline and am trying to reduce my file size. When a user answers a question correctly, I would like for the course to ask her if she would like to see the problem worked or move on to the next question. Originally, I did this via a second slide (meaning if incorrect the user would branch to one slide, if correct, another). I just discovered Slide Layers and think this may be the most effective way to handle this.
My question is - what takes up more space in a story - a slide or a slide layer or do they generally take up the same amount of space?
