In pull requests, the block of "Cannot merge " error message followed by a list of conflicting files is currently placed between the input box and the “Comment” button.
The problem is that the list of the conflicting files can grow very large if the PR author base their feature branch on the wrong branch. When other people add comments on such PR, they’ll need to scroll all the way down to the bottom of the page to reach the “Comment” button to submit what they just wrote.
The following screenshots demonstrate such situation. Each of them containing the beginning and the end of the 2624-line file list.
It would be great if the list of the conflict files can be folded when there are many of them to avoid bombarding pull reqest UI.
