If you single tap on a comment it closes the chain.
Liftoff!
A mobile client for Lemmy running on iOS and Android
it’ll close the children, but i would like a feature to collapse the parent comments
How would you get the parent comment back? I'm not understanding what problem this solves
Say there’s a post with a deep comment thread replying to one of the top-level comments. You start reading replies to one of the top-level comments and you’re done reading that conversation now (you didn’t each the end of the sub-comments and want to jump back to the main conversation to see other top-level comments). This feature would just collapse the current context you’re in (all sub-comments from the top-level comment) so that you can easily move on to other top level comments without having to scroll all the way back up to collapse that entire thread.
That top-level comment is now just collapsed, so if you wanted to dig back in again you just tap to uncollapse it as if you had collapsed the top-most comment yourself. It’s really just a shortcut to collapsing the top-level comment without having to scroll back up.
This isn’t a novel idea - apollo did it, it’s probably the #1 thing I miss that I haven’t seen any of the lemmy apps I’ve tried tackle.
