Really cool feature ideas indeed.
Copying to the clipboard is soooo useful when working with other image software, so you don't have to go and open a file, you can just paste the image right in.
In fact, we have a setting for this, I made a video a few days ago that shows how to do it:
Unfortunately, the Responsive Design Mode doesn't seem to honor this setting. @jryans might know if there is already a bug being tracked for adding this.
As for taking full page screenshots, there is a quicker way:
- go in the settings panel
- check the Take a screenshot of the entire page button in the Available Toolbox Buttons section
- this adds a new camera icon into the DevTools toolbox toolbar
Now, clicking this button will take a screenshot of the entire page, whether you are in Responsive Design Mode or not.
However, the camera button in the Responsive Design Mode toolbar always only takes a picture of the visible viewport. Here again, maybe we should honor a global setting that applies to all buttons in DevTools?
