My guess is that this is the first time we extract some rendering logic from "ui.ts". So I wonder if a "ui/index.ts", "ui/todos.ts" is better

[nerrad]

Fair point. To make sure I fully understand though, you mean we'd have ui as a subfolder in the path? So apps/cli/ai/ui/.... If so, that would help organize things a bit better. But can also be done as other helpers/tools are developed.

[youknowriad]

yes, that's what I meant, yeah no urgency here
