I love the addition of a way to navigate to the next/previous top level comments. I have a suggestion about the way it is implemented.
Currently you have to have a top level comment selected to activate that menu, but sometimes a comment chain is quite long so you end up having to either scroll up or down a fair way to get back to that menu.
I'd like to suggest a UI change, using a screenshot from Slide for Reddit as an example, you can see there's a floating, translucent bar along the bottom of the screen (just above my phone's navigation buttons) which you can press and it finds the next/previous top level post no matter where you are in the current chain.
Yes please. RIF had it and I do miss that feature. Though I need to mention that Connect has made improvements in leaps and bounds recently and has truly increased my satisfaction level with Lemmy (thank you to the devs).
