RFC 3 · Where does the navigation rail belong in a vertical-first interface?

[jihoons0]

Labels: RFC navigation

Horizontal apps place navigation at the bottom (thumb reach on mobile) or the left (desktop), keyed to the primary reading axis. In a vertical, RTL interface the primary axis is down-the-column and columns flow right-to-left — so the "natural" home for a rail is genuinely unclear.

Where it shows up here: tabs, chapter-navigation, and the chrome of Vertically Verse.

Open questions:

• Does the rail belong on the right (the reading origin) or the left (the reading destination)?
• Bottom-bar thumb ergonomics vs. reading-axis consistency — which do users forgive?
• Should the rail itself be set vertically, and if so, top-to-bottom or bottom-to-top?
