Created attachment 152259 [details]
Example for very hard to differentiate comments
1) Open Attached file
( I don't know how to reproduce to make the comments blue, so the attachment is the easiest way. Here I copied-to-clipboard between a VM and a host. )
2) Comments, that are not shown in yellow (in my case it's blue comments) are very hard to distinguish from each other . Yellow comments receive a frame, when the cursor hovers over the respecting comments.
1) Regardless of the comment color, the behaviour regarding emphasizing focused comments should be the same
2) Maybe a more obvious way of showing the focussed comment, when the text cursor is on the text element, that was commented
3) Maybe "Ctrl + mouseclick on comment-triangle" could let the cursor and view jump inside the comment box
In LO 184.108.40.206 first comment is blue, other comments are green. I don't know where to define comment background.
In 220.127.116.11. first comment is yellow, other comments are green and I can't see a difference, if cursor hovers over a comment.

Comments are colored by authors, so blue is your vm and green the host. The referenced place in the document is in fact not so easy to spot but take a look at the line, it changes from dashed to continuous. Regarding the readability I make this a duplicate of an older issue. Feel free to reopen if you disagree.
