No indication that a file has comments

Current Behavior

When I open a file that somebody has commented on, I don’t see that there is a comment. As you see in this screenshot, there is no indication that the file has comments. Only after clicking the comment button to open the sidebar, the comments appear.

This severely restricts the usefulness of comments. For example, I use comments to indicate that the content of this file is outdated or needs to be read with caution.

Suggested Behavior

I see two (not mutually exclusive) options:

1. When I open a file, the comment sidebar automatically opens if there are comments.
2. The comment button at the top-right (see screenshot) appears in an alert color, e.g. red. In addition, the number of comments could be shown next to the button.
