Sure. It is inconvenient. But it's better than realizing after 5 months that you are missing half of the conversations just because you are not using the full power of Nostr. The whole point of this stack is to use multiple clients to see things with different eyes. Otherwise we are not that different from Twitter.

It's amazing though that instead of trying to amend the protocol's flaws the usual answer is "it is so by design" and the solution is for example "use many clients". And I say this respectfully and fully acknowledging the huge work you pour in here. You just can't expect the average user to use three clients just to see if someone mentioned him/her.
