An Ask Haruno button or the chat button in the toolbar opens your chat in a column beside the page you are on, so you do not lose your place.
Mac appAvailablesince 1.3.53
Windows appAvailableOn every page except Chat. There is no special case for company pages.
You can talk to Haruno without leaving the page you are on. The chat opens in a column on the right, and the page stays where it was.
It is the same chat you have on the Chat page, not a second one. What you wrote and what Haruno answered is all there.
Open it
Click an Ask Haruno button on a page. For example, on a company's page it puts your question in the message box and opens the column. It does not send anything. You read it, change it if you like, and press Return. See Ask Haruno about the books.
Click the chat button in the toolbar. Its tooltip says Show Chat Panel.
Choose View ▸ Show Chat Panel (⌥⌘0).
The button is on every page except Chat, where the chat already fills the window. On the Chat page, the same key and menu item show and hide the side panel instead. See The side panel and Activities.
Close it
Click the cross, which says Close chat panel. Or click the toolbar button again, which now says Hide Chat Panel. Or choose View ▸ Hide Chat Panel.
The column stays open as you move between pages, until you close it.
What is in the column
A header with the title Chat and three buttons:
New Chat starts a fresh conversation without leaving the page. It is off while the chat is empty.
Open in Chat moves to the Chat page, where the same chat is wider.
Close chat panel.
Under the header is the chat, with its message box. Drag the edge of the column to make it wider or narrower. Haruno remembers the width. If the window is too narrow to fit both, the column floats over the page instead of squeezing it.
Previews and activity
A document preview and the Activities list live beside the Chat page only. If you ask for one from the column, for example with the Preview button on a file card, Haruno moves to the Chat page first. See Preview panel and The side panel and Activities.
When something else takes the column
On some pages the column shows something other than the chat for a while, such as a page of a company's source PDF beside the figures read from it. Pressing the chat button, choosing Show Chat Panel or pressing Ask Haruno brings the chat back.
When Haruno starts again
The column comes back after a relaunch only if the chat has something in it, a conversation or a draft, or if a company's page is open. Otherwise it starts closed.
Who has it
Everyone, in the normal view and the advanced view. It came with version 1.3.53.
What to tell a customer
You can ask Haruno about the page you are looking at without switching screens. The answer arrives next to the numbers, and the chat is the same one you would find on the Chat page.
