I ended up writing most of my school essays in it. You could start with a high-level outline and recursively flesh it out until you had a complete document. The tree structure made it really easy to reorder sections at any scale.
There is a successor called Opal - the last version of Acta was in 1993, and the last version of Opal was no later than 2007, so it's dead too.
