When I go to T43, it reads 75 older changes are hidden. Show all changes.. This makes in-browser find difficult and requires me to click a link in order to see the full task. We should either make this comment hiding/collapsing configurable per-user or simply disable it across the site. Hiding/collapsing comments directly hinders and harms user-to-user communication and results in wasted time as people make duplicative comments.
