Disable card view (which is the default for new installations) + choose smaller text size would achieve more or less the same. I have already gone thru few iterations of compacting the UI and I'm afraid I can't squeeze it anymore :(
Thanks for the reply. I really like the "comment search" feature in Relay based on time (show and jump through comments added in last X minutes), words (jump through comments that contain certain words), jump to comments based on author (OP, me), etc. There are many more comment search parameters, but these are my favorite.
I already have similar request in my backlog. This is gonna be tricky, because I don't have all comments up front as they are loaded on demand (even for saved comments - loaded on demand from cache).
I have something similar in mind but haven't get started yet. It can be done via HN API, but it can only be done at regular interval (polling), as I don't use Firebase but raw web API.
Not op but I use both Relay and Materialistic and I find myself swiping from the left to get back to the main page after reading the comments (muscle memory after using Relay for a long time). It would be great if you could incorporate this into your app. Either way, its a great app!
