Pin, set aside, mark as done

Besides archiving or flagging a message, Heron offers three gestures to organize your inbox.

Gesture	What it does	Shortcut (desktop)
Pin	Keeps the message at the top of the inbox	P
Set Aside	Takes the message out of the inbox, with no return date	S
Mark as Done	Marks as read and archives, in one step	D

You’ll also find them in the Message menu (desktop), a message’s menu (right-click or More Actions) and among the swipe actions.

Pin

A pinned message stays in the Pinned section at the top of the inbox until you unpin it. It also appears in the Pinned view in the sidebar, even if you move it to another folder.

To remove it: Unpin (or P again).

Good to know: pinning is different from Flag. Pins are kept by Heron and synced across all your devices, but they don’t show up in other mail apps.

Set aside

Handy for an email you’ll deal with “someday”, without a specific date. The message leaves the inbox and goes to a Set Aside folder in its account, created the first time you use it. You’ll find it in the Set Aside view in the sidebar.

To bring it back: open it and choose Return to Inbox.

Because it’s a real folder on your mail server, you’ll see it in your other mail apps too.

Need it to come back on its own at a specific time? Use Snooze instead.

Mark as done

Mark as Done marks the message as read and archives it in one go. A single Undo reverts both.

Undo

After each of these gestures, a notice at the bottom of the screen offers Undo. On desktop, ⌘Z (Ctrl+Z on Windows and Linux) works too.
