Thats the feature I suggested, but he rejected. :P How would you implement it?

I suggested swiping horizontally on a comment would collapse the children.

I have no idea what would trigger the collapse, but it's extremely annoying to browse this way. Especially on submissions with a lot of comments, you have to go through a huge list of worthless comments to find the next "good comment".

Either a thread collapse or a "skip to next comment on the same indentation level as this" would solve that problem.

I just had contact with the author, he seems to be willing to acknowledge the issue, but unwilling to implement a fix. So that's a shame, made me waste some money.
