# Improve mobile presentation tabs, annotation popovers, and auth layouts

**Version:** v5.31.0

**Published:** June 10, 2026

This release improves the responsive design for smaller screens by collapsing the side-by-side editor view into tabs, fixes annotation popovers and modals to display at proper widths, and corrects issues with scheduled drafts and authentication component layouts.

> [!NOTE]
> Sanity Studio v6
> v5.31.0 marks the final v5 of studio. We will be bumping to a new major, v6, and this will include deprecating support for Node.js 20 (which has reached EOL) and a few additional changes. [Read more on v6 here](https://www.sanity.io/blog/sanity-studio-v6).

## Switch between Presentation and Structure on mobile

Presentation now adapts to narrow viewports. When the window is too small to show the preview and the document editor side-by-side, they collapse into a tab bar at the top so you can switch between “Presentation” and “Structure” (and “Navigator”, when configured) one pane at a time, instead of a cramped split view. Wider viewports are unchanged.



## 🐛 Notable bugfixes and improvements

- Fixes Portable Text annotation/object edit popovers, such as link annotations containing a reference field, rendering too narrow when the type set `options.modal` without a `width`. They now use the default width, so embedded reference fields and their autocomplete results are usable.
- Fixes a bug in scheduled drafts where viewing a document from an archived draft showed an “Add to release” option that errored when clicked. The archived draft now shows the correct “Archived release” banner.
- Increases the width of some authentication components, including the workspace selection screen.
- Studio will now show a warning if auth config resolves to no providers.
