1515875 - [meta] Track Changes M2 (aka export)

Status: RESOLVED FIXED

(DevTools :: Inspector: Changes, enhancement, P3)

Description

[Patrick Brosset <:pbro>]

Track Changes M1 shipped with Firefox 65.
This first milestone provided the ability to track all CSS changes made within the inspector panel.
The changes are displayed in a new Changes tab for users to review.

M2 (aka export) will add the ability to export these changes in a useful way.

The list of what we intend to work on:
- add a way to copy & save the list of changes
- add a way to copy & save the list of changed CSS rules (complete list of declarations with changes applied)
- add a visual indicator to the Changes panel tab when data is available
- add more telemetry probes to the Changes panel
- fix outstanding bugs from M1 release

Release Note Request (optional, but appreciated)

[Why is this notable]: This noticeably improves the Changes panel as it provides new exporting features to it, so we should let our users know about it
[Affects Firefox for Android]: No
[Suggested wording]: The DevTools Changes panel now supports copying modified CSS. You can either copy the full changes or individual changed rules.
[Links (documentation, blog post, etc)]: The docs are on MDN here but they have not yet been updated with these new features.
