I like this a lot. I haven't tried making a tour yet (got turned off when I saw I needed an account), so I'm not sure what options are available, but... I feel like there could be more visual emphasis on the content being isolated. The Drawium annotations look a bit too similar to the content. Maybe that is because the background color of the demo page is close to that of the annotations, or maybe it is because the annotations appear to be in the same layer as the highlighted content (perhaps a light-color shadow would make the annotations stand out more?). It would be more difficult to implement, but I wonder if having a softer edge around highlighted content would help (gradient fade to black). Or maybe add a shadow around the highlighted area to "raise" it out of the page? Maybe timed transitions would help. What if the transparent overlay fades in around the content being shown before the tooltip, rather than appearing instantly and at the same time? Isolate first, then explain. I see that the API offers additional options. It would be nice if the demo tour on the homepage includes a variety of these options. I also instinctively tried to use the left/right arrow keys on my keyboard navigate through the demo tour. Next/previous key bindings may helpful. It's not clear how far along in the tour I was. How many elements is the tour explaining? Do I have to click "Next" a hundred more times? What if there is a number somewhere in each annotation showing progress (eg. "3/8").
