In Proton Mail, when a long email thread accumulates, each reply-all can include all prior messages, requiring extensive scrolling. To simplify this, it would be incredibly helpful to introduce chevron-style indicators to collapse or expand email threads. Additionally, having up and down arrows to move between emails would mean we don’t have to scroll like crazy when someone replies-all. These additions would make handling large conversations far more efficient and user-friendly, similar to the Apple Mail app.
