Every streamed token called scrollTo("bottom"), so scrolling up to reread something mid-answer was yanked back on the next token. Now any scroll the user makes (wheel, trackpad with momentum, scroller drag, the keyboard scroll keys) pauses following, and it resumes only if they settle back at the bottom, send a new question, or open a conversation.

Pinning is judged on user scrolls only, never on the stream's own scrollTo: that one can land a hair short of a document that is still growing, and judging it would unpin the stream by itself.

📝 Walkthrough

Walkthrough

The chat now tracks whether it should follow the latest content. Content updates scroll only while following is enabled. Scroll-wheel, live-scroll, and keyboard input pause following. After 0.2 seconds, following resumes when the conversation is within 8 points of the bottom. New submissions and conversation presentation enable following.

Changes

Chat Scroll Following

Layer / File(s)	Summary
Follow state and content scrolling Sources/QuickAI/ChatViewModel.swift, Sources/QuickAI/ContentView.swift	ChatViewModel tracks whether the chat follows the latest content and resets this state for new submissions. ContentView scrolls for content updates only when following is enabled, and enables following when a conversation opens or the scroll view appears.
Scroll input and follow restoration Sources/QuickAI/PanelController.swift	PanelController monitors vertical scroll-wheel events and live scrolling, and pauses following for user and keyboard scrolling. It checks the distance from the bottom after 0.2 seconds and restores following when the distance is at most 8 points. Vertical offset calculation handles flipped and unflipped document views.
