MailFlow

New Features

• Resizable sidebar — drag the divider between the sidebar and message list to set your preferred width. The width is saved and synced across devices.
• Default reply action — set Reply or Reply All as the default action for the reply button in Settings → Message List. The keyboard shortcut (R) and button label both follow your preference.

Fixes

• Compose From address — the From field now defaults to the currently selected account (or last-used account when in unified inbox) instead of always defaulting to the first account.
• Favorites context menu — mobile — long-pressing a favorite folder now correctly shows the context menu on iOS without triggering the native "Copy / Look Up / Translate" callout or causing a page layout shift.
• Favorites context menu — desktop — right-clicking a favorite folder no longer silently failed when the account's folder tree had never been expanded. Folders are now pre-fetched on startup for accounts with favorites.
• Mobile toolbar overflow — action button text labels (Reply, Forward, Archive) are now hidden on mobile, preventing the trash and star icons from being cut off at narrow viewports or larger font sizes.
• Swipe gesture vertical drift — setting touch-action: pan-y on swipeable message rows reduces unwanted vertical scroll movement during horizontal swipe actions.
• Preference sync — the default reply action and sidebar width preferences are now correctly persisted to the server and sync across devices on login.
