When reviewing a MR, I sometimes want to look at (and even add comments to) code that isn’t displayed in the MR window.  With Phab there was a “show 20 more lines” link, and even “show the whole file”.  How do I do that in GitLab?

When submitting a review, I often want to add an overall comment, not related to  a particular line of code?  How do I do that?

Thanks
