Description:
I have a PPT slide that contains a massive amount of notes (I can't share it because it's proprietary). 

When I am in Notes mode, the slide often goes above the top of the screen. When I want to change slides, there is no feedback in the Slides toolbar indicating which slide is currently active.

So I have to click around, scroll back up, or whatever to figure out where I am and move to another slide

Steps to Reproduce:
1. Have a document which uses a lot of notes (ideally one where you need to scroll notes until the Slide design is off the main screen)
2. Click anywhere in the notes area in Notes mode
3.

Actual Results:
The slide highlight that appears normally when you are working on a slide disappears. When you have a lot of slides, it makes it difficult to know where you are in the presentation.

Expected Results:
I would like some sort of indication for the currently active slide. It could be a highlight, a red border, anything that makes the currently active slide look different from the rest. It's a usability issue.
