The sidebar

Home is the landing screen: your calendar for the day, if you have one connected, and your recent calls. Personal holds calls that are not in a project yet. Below that, every project you have access to, and New project.

⌘K opens the search palette. It covers projects, recent calls and quick actions (including starting a recording), so it is usually faster than clicking through the sidebar. Nothing matching reads No matches, with the hint to try a project name or part of a call title.

Inside a project

Search calls filters the project. Calls are grouped into upcoming and Past calls, and long lists load more as you scroll.

The search palette open with project and call results
⌘K reaches projects, calls and actions from anywhere.

Questions

What is Personal for?

Calls that have not been filed into a project. Junior describes them as calls to file when you are ready. It is a staging area rather than a project. File things out of it so the people who need them can find them.

Why can I not see a project a colleague can?

You see projects you have been given access to, so lists differ between people. Whoever set the project up can add you.

I cannot find a call I know I recorded.

Check Personal first. An unfiled call is not in any project. If it is not there either, it may not have finished uploading, so look in Saved Calls (⌘3) for something still queued. See a recording will not save.

Does ⌘K search inside transcripts?

It searches names and titles, not the words inside every call. To search within one call's transcript, open it and use the transcript's own search. For searching across transcripts, use Junior on the web.

Are these the same calls I see on my phone?

Yes. It is one set of calls shown in both apps: record on your phone and it appears here, record here and it appears there.
