Have you noticed an eye icon 👁️ in the top right corner of Mastodon threads? Do you wonder what this does?
It's actually a really useful feature:
If you're browsing a thread that contains posts hidden by Content Warnings (CWs), you can click the eye to toggle them all open or closed. This saves you having to open each post one by one.
(The eye is still there even if there aren't any CW posts, but it will do nothing.)
