Both plot points and map pins will soon have separate revealable text and GM-only text. This is one of those small things we've been working on when there's some spare time in parallel with the focus on Player Edition. Ideally, it's something we can finish up soon after returning from GenCon.
In the meantime, the original concept was that plot points would be relatively brief summaries intended for consumption by players. We envisioned users associating the plot points with topics (typically Scenes), where the topic would contain the bulk of the material spanning multiple snippets that are individually revealable.
Hope this helps!
