hmm other than editing the post with a quote from the post being replied to or something like that, I can’t think of another way.
One thing that might help is adding “to topic” to the footer topic button label, so it says “reply to topic” to make it more obvious and distinguish it from the post reply buttons:
in common - css of a theme component:
#topic-footer-buttons {
.topic-footer-main-buttons {
button.btn-primary.create {
span.d-button-label:after {
// Adding this content after Reply
content: " to Topic";
}
}
}
}
