Flow Mode on Mobile Devices

Kharden06

Hello,

I really love using Zotero on desktop for reading and taking annotations. However, I wish the mobile app had a "flow mode" for ePub files. This missing feature is the only thing keeping me from using Zotero on mobile.

Thank you for creating this perfect app

What do you mean by a "flow mode"?

I'm sorry for being ambiguous.
I meant the Page Layout setting

As far as I know, EPUB support is being tested on Android and already supported on IOS.

Yes, iOS has ePub support, but what I meant is iOS doesn't have all the "Page Layout" features that the desktop version has. The iOS version just has paginated (paged) layout, not scrolled (flow).

Hi, I'd like to pick this thread up and offer to implement scrolled mode for EPUBs in the iOS app.

To make sure we mean the same thing: on desktop, View → Scrolled switches an EPUB from page-by-page layout to continuous vertical scrolling. The Android app has the same option under Page Layout (Paginated / Scrolled). The iOS app only has the paginated layout today, with no way to switch.

From reading the code, this looks like an iOS-only change. The shared reader (zotero/reader) already supports both modes, and the Android app just calls `setFlowMode` on the view and stores the choice in its reader settings. On iOS, `HtmlEpubSettings` only has an appearance setting and `createView` doesn't pass `flowMode` in the view state. So the work would be: add a Page Layout row to the EPUB settings popover, persist it in `HtmlEpubSettings`, pass it in the initial view state, and call `setFlowMode` when the user changes it. Snapshots wouldn't be affected.

I'm a developer and happy to do this and open a PR against zotero-ios. Two questions before I start:

1. Would you accept a PR for this, or is it already planned or in progress on your side?
2. Any preference on the UI? I'd mirror the Android app: a Paginated / Scrolled segmented control in the reader settings popover, shown for EPUBs only.

Thanks!
