The left column#

From top to bottom:

Protocol and Patcher: the instructions the model gets, shared by all worlds. You don't have to touch them. See The Protocol and the Patcher.
Your worlds, each with its Story, its Cast (the characters, you and the audience), its Places and its Games.
Import world, just above the first world: loads a world from a file. See Import a world.
Below the worlds, once unlocked: Stories, the Vault of Mipsy's stories. See Mipsy's stories in Roller. Drag the line above it up or down to give it more or less room.

Next to most items you see a rough length (for example ~28), or empty when nothing is written yet.

You can make the left column wider or narrower by dragging the gap to its right.

The status line#

The line next to the token gauge tells you what Roller is doing: Waiting for the cast…, Thinking… 12.4 s, Playing… 20.1 s, Done in 31.0 s, and so on. Problems show up there in red.

Waiting for the cast… means your turn has been sent, and the model is reading the whole play so far before it starts writing. In a long game this can take a while.
Thinking… means the model is working on its answer but hasn't started writing the turn yet.
Playing… means the characters' answer is arriving on the stage.
