Why aren't comments collapsible

[David Naylor]

We live in the "timeline" era now where comments on social media platforms only take up so much vertically space and then you have to expand them to see the full comment.

Wouldn't it be obvious to implement this on Trello when we have multiple comments running vertically down the comments section - especially on mobile.

Male all the comments expandable/collapsible. Default would be collapsed.
