Smooth scrolling

[maartenbreddels]

When a cell gets executed (shift enter), the page may scroll down. If the cells are big (and especially if you are watching someone else work with jupyter lab), it is difficult to see what is going on. If instead, the page would scroll in ~0.2-0.3 seconds, I think it would be much easier to follow what is going on.

Do you think a lag like that would be frustrating to quick users? I think it's worth experimenting, but be aware that sometimes that scrolling is actually triggered by focusing and is out of our control.

I think it should be quite quick (0.3 is already quick I think). Also when you would use the arrow keys, the notebook just 'jumps' to the location. If I had some idea (because of a smoother scrolling) where it went, I at least know if I should scroll up or down, and have an idea of how much.

But I agree, it should not get in the way. For instance, doing 10 executions shouldn't pile up to 3 second scrolling. The max scrolling time (between action and arriving) should be max this 0.3 seconds I think.

Do you have smooth scrolling turned on for your browser?

Should be fairly easy to try with scroll-behavior: smooth on the notebook widget. See https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-behavior.

I experimented with it for a bit but didn't find it to be an overall improvement. This could be an issue with the browser implementation or just my expectations.
