Version 1.22.0 was just released with support for viewing deeply nested comments.
This feature is SUPER cool and something I've wanted to do for a while (despite not making a Github issue for it). I can only take credit for the code though, because the design is inspired from Apollo.
There's two parts to the experience to viewing deeply nested comments:
Load parent comments
Example
When you're viewing a link to a single comment and the comment is nested greater than three layers, you will see a "Load parent comments" button:
When you tap it, you can continue to load parent comments, all the way back to the root comment. And what's cool about it is since you're viewing a single comment chain, we can take advantage of that and forgo the indentation:
Even though the parent chain isn't indented for a given comment, the comments still have their unique nesting colors!
Continue Thread
When comments get too nested for a single page, you'll see a "Continue Thread" button:
Tapping that brings you to a new page to continue viewing the thread (notice page title is "Thread" and initial comment is highlighted):
You can keep doing this over and over again for very deeply nested conversations, to the bitter end!
