Oh boy, I got good news for you. That is a great feature that I am also looking forward to and I already saw it in the github pull requests! The preview looks really good (better than e.g. the current implementation in Boost for Reddit which is way too small and disappears after some time). Not sure if it is in the next version but it should hopefully be added soon!

Quick comment navigation

The latest version (0.0.35) is out already and has this feature. So far it's only on github I think, but you could install it from that apk if you can't wait for the play store release.

Some other things might be broken (default sort no longer seems to be remembered for instance) and you'll have trouble connecting to instances that are not yet on lemmy 0.18 (this might be the majority currently; lemmy.ml is a big one that already updated), but apart from that, it's looking good.

You can collapse the main comments which will also get rid of all the subcomments
