Auto-scroll toggle: pause scrolling while reviewing earlier output

[mellanon]

Context

When an agent is actively working, new messages at the bottom pull the view down automatically. This is helpful when following along, but disruptive when trying to read earlier output.

The Problem

If I scroll up to review what the agent did earlier (trace, reasoning, commands), the next new message snaps me back to the bottom. This makes it difficult to:

• Read through a long trace
• Understand the agent's reasoning on an earlier step
• Review output while the agent continues working

Related to #155

Issue #155 addressed the opposite concern (auto-scroll not working). This is the complementary UX: being able to pause auto-scroll when reviewing.

Possible Approaches

Option A: Scroll position awareness
Only auto-scroll if the user is already at (or near) the bottom. If they've scrolled up, stop auto-scrolling until they manually return to the bottom.

Option B: Toggle button
A visible toggle: "Auto-scroll: ON/OFF" in the agent panel header.

Option C: Keyboard shortcut
A hotkey to toggle auto-scroll pause (e.g., CMD+SHIFT+P for "pause scroll").

This isn't supposed to happen, will dig into it.

Thanks for reporting this @mellanon! 🙏

This has been fixed in commit b37f1b3 — we removed the unconditional auto-scroll that was snapping you back to the bottom. Now AI mode respects your scroll position: if you scroll up to review earlier output, new messages won't interrupt you. You'll see a "New Messages" button to jump back when you're ready.

This will be included in the next release.
