Notify user if sent/edited message is outside current narrow

[kaustubh-nair]

For example, if a user is in topic narrow and edits a message's topic then it would be moved do a different narrow. We should probably display a message in the footer if this happens.

@kaustubh-nair Could you explain how I can resolve this?

I'm new to zulip's codebase.

[kaustubh-nair]

@avats-dev You can use model.narrow and other narrow-related methods in the model to detect narrow changes, and use view.set_footer_text() to display the message.

Thanks @kaustubh-nair for the help, I'll try and get back to you if I need some help.

Hi @kaustubh-nair, I have a couple of questions:

1. If a user edits a message topic in a narrow, then he already knows where the message is moved now because he edited it, so why is this needed. Am I missing something?
2. If we display a message in the footer, what should be the message body?

@zee-bit

1, That is correct. Though we want to give the user a pointer as to why the message disappeared from the screen.
2. That's up to you. It's a small enough detail that we can modify during the PR review, if needed. Feel free to take inspiration from the web-app.
