Boost For Lemmy

Hi there, I recall on Boost for Reddit that I could open a post, and collapse comment threads to a single line, which was excellent - it made it really easy to scroll past comments I've already read or decided I'm not interested in, and I might be wrong but I think there was an option to auto-collapse everything but new comments? On Lemmy, replies are collapsed but the comment I tapped on remains open, regardless of whether it's the top of a comment thread or one mid-conversation. So best I can collapse to is a post and all of its top-level comments.

The other one is that on Reddit I was able to create a group and add subs to it. That group would appear in my sidebar, and when opened it'd be a feed of those subs without needing to join each one (which makes 'Subscribed' really busy). On Lemmy I can add favourites to the sidebar, but they show up in the list individually - I'd like for example to have a single entry in that list called Home Tech, when I tap it I get a feed of only home automation or homelab stuff. Then another one just for memes. Etc

If these settings already exist and I've just missed them please let me know, otherwise I'd really appreciate if they could be added to BfL.

Thanks for the fantastic app and ongoing support!
