Thesis Auto scroll in AI chat should follow the user intention and never fight the user
TLDR
- Follow when the user is at the bottom
- Stop following when the user scrolls up
- Keep it fast with virtual lists when messages get long
1) What auto scroll really means
Auto scroll is just a policy
When new messages arrive
Decide whether to keep the view pinned to the latest content
2) A simple rule that works
- If the user is near the bottom
Follow
- If the user scrolls up
Pause
- Show a jump to bottom button
3) How to detect user intention
Use signals like
Distance to bottom
Scroll direction
Recent input activity
4) Performance basics
Long chats can create too many DOM nodes
Virtual rendering keeps only what is visible
Bottom line
Good auto scroll is simple
It respects the user and stays fast
