Feature description

https://github.com/SimpleMobileTools/Simple-SMS-Messenger/issues/218: At the moment you can globally search messages. It would be nice if you could search individual conversations (search button within conversation view).

For example, how it is in Signal.

Why do you want this feature?

Searching in conversation will refine and facilitate many more searches than globally. It will also speed things up, as there will be far fewer messages to search through.

Additional information

There is an unimplemented pull request in Simple Mobile Tools (https://github.com/SimpleMobileTools/Simple-SMS-Messenger/pull/665) that would probably add this.

I would add it to menu in conversation, like signal has it
