Feature Request

When the agent is currently processing a prompt, newly submitted prompts are queued and will be processed afterward.

It would be useful to have a way to cancel/remove a prompt that is currently queued before the agent starts processing it.

Example

1. The agent is processing Prompt A.
2. The user sends Prompt B, which gets queued.
3. The user realizes Prompt B was incorrect or no longer needed.
4. The user should be able to cancel Prompt B while it is still queued.
5. Prompt A should continue running normally.

Expected behavior

Prompt A → RUNNING
Prompt B → QUEUED → CANCEL ❌
Prompt C → QUEUED

After cancelling:
Prompt A → RUNNING
Prompt C → QUEUED

Cancelling a queued prompt should not interrupt the currently running task.

Motivation

This would be useful when a user accidentally sends a prompt, changes their mind, or realizes that a queued instruction is no longer relevant before the agent starts processing.

the Queue/steer settings control was removed in ae7e2eb @itsflaid

any specific reason it got removed @adamdotdevin ? I can take this up if we want it back

Perhaps this issue should have a "Regression" tag?
As a new user I was quite annoyed that one had to interrupt to cancel a queued prompt, and then, if running local CPU only near full context, perhaps throw away hours of good reasoning... Is there a fork of opencode that can do this?
