Do you use Mastodon's web interface? Do you get frustrated when viewing a thread with content warnings because you have to open lots of CWs individually?
There is a solution to this problem: just click the eye icon in the top right corner to toggle all the thread's CWs open or closed. (If it doesn't seem to work, click again. It's a toggle switch!)

@FediTips oh my god!! they should improve the UI so that people actually discover this naturally (but thanks for the tip!)
