Explore diffing for notebook cells

Overview

In the editor, we have existing patterns for showing source control (scm) decorations, which is also one of the entry points into source control diffing. This issue is to explore what scm decorations look like within the context of notebook cells.

Considering there are quite a few open questions for rich diff, we started to explore an enhanced text diff view for notebook to help us understand the best way to present content changes to users. A prototype based on the design mock up from @misolori :

Here's the original mockups for the simplified visual diff/enhanced text diff:

Will there be an option/setting to not consider metadata?

[rebornix]

@claudiaregio we thought about adding something similar to "Show leading/trailing whiteface difference" in normal text diff editor before.

In our scenario it would be "Show/hide metadata difference" or so. Is this something close to what you have in mind?

[miguelsolorio]

I think having a similar action (toggling metadata) would be great, I'd imagine most users wouldn't want to see this info. I also assume that this would be a setting a user could also set?

[claudiaregio]

@rebornix close but I thought it would have a better place as a setting like @misolori mentioned, as opposed to something that is surfaced to user as a toggle option.

[rebornix]

good to hear we are talking about the same thing. Yes sure we will introduce this as a setting and an action/command to toggle its value.

+1 on the option to toggle metadata.
Will there be an option to show/hide output?

I think this can be closed, reopen if you want to keep it for anything
