Missing features?

Curious if Voyager has options for the following that were available on the Reddit app:

A down arrow/next top level comment button to quickly navigate through comments. In the Reddit app this a floating down arrow button
pull down on your feed to refresh and see new posts

Not sure if I’m missing them or if they don’t exist

You can enable the comment navigation button using: Settings -> General -> Comments -> Show Jump Button.
You can click a comment to collapse it and all children so I’m not sure the arrow feature is needed, if I’m understanding it correctly.
Comment navigation - No

Pull down refresh - Yes
Double tap on a comment to “fold up” lower level comments. Is that what you mean?

Already exists as far as I can see
