We do a ton of eLearning development in Storyline. A recent client asked if there was an easy way to add a percentage complete area on each slide so the learner quickly knew how much content remained to be viewed. Thanks to a fairly recent addition to Storyline 360, adding such a feature to a project is simple (it's also easy to add slide numbers).
If you'd like to follow along with me, create a new Storyline 360 project and insert 10 slides from the Content Library. (I went with the Affinity template but you can use any of the templates.) Each of the slides in my sample project are represented in the menu shown in the image below (at the left).
