Moving bug to (new) 'Impress Remote' product.

This will be very useful. I'm going to try to explain why. 

1. When you're presenting, it's important to preview what's going to happen in next slide. But there is not "picture-in-picture mode" or similar, to see next slide. 

2. Instead that, you can use "Presentation console" but you will need another monitor. In pre-pandemic situation, you will have a projector (for sure). So will be a possible and good scenario. 

3. But now, in several cases, you will present using video-call with screen sharing. If you only have 1 monitor, one good solution is using "Impress remote" and grid view to see what is goint to happen next. But, thumbnails are too small to see it. 

Would be great can make them bigger.
