If Frank or anyone else wants to do this, go to Settings in your User menu. At the top choose Comment Preferences.

There you can choose Nested, for example, that makes it easy to see what comments reply to which. Specify a number up to which you want this (I have 200, for example). If the thread gets longer (and unwieldy), the display switches to the second choice you indicate with a + sign. (I have Dynamic Threaded, meaning nested headers I can click on to open the comments).

Below these options you have View (I don't know why one would not leave it on default ie Mixed), then Sort. There you can choose Ignore Ratings if you wish. To the right you can opt for Oldest First (oldest comments at the top) or the contrary.

I won't go into the rest for now, this is really not on-topic...
