The workspace has three parts, and once you see the pattern the rest of the app is predictable.
The sidebar, on the left
Your clients, and everything about the one you have selected: their workouts, the exercises inside them, and the buttons for their weight, measurements, nutrition, habits and goals.
It resizes. Drag its edge to make it wider, collapse it to icons when you want the room, and expand it again. With a long roster, Load more brings in the rest rather than loading everyone at once.
The grid, in the middle
Every client as a card. It is the only place that shows the whole roster with its numbers, which makes it a sensible first stop. The thing you are looking for is usually the client whose numbers changed.
Panels, from the right
Messages, notifications, videos and forms slide in from the right rather than taking you to another page. You keep your place in the grid while you deal with something, which is the main reason Basecamp is faster than the phone for getting through a backlog.
Super Search
One field across everything you have. Type plainly (the helper text tells you natural language works) or add filters when you want precision. Results carry their own context: when a video was uploaded and how many views it has, how many responses a form has collected, how many completions an exercise has.
It is worth learning early. On a roster of thirty, searching for a client is faster than scrolling for them every single time.
If your layout keeps resetting
There is a specific cause, and Basecamp names it: functional cookies are off. With them disabled, your sidebar layout, language and other workspace choices reset to defaults every time you sign in.
The notice appears in the sidebar itself rather than leaving you to work it out. Turn functional cookies on in your cookie settings if you want your layout to stick. If you would rather not, nothing is broken. You set the sidebar up again each time you sign in.
Sharing the Academy with a client
There is a Copy link control that puts an Academy link on your clipboard. Useful when a client asks something that already has an article: paste it into a message rather than typing the explanation again.
