What do Expand all and Collapse all do on the P&L?

They open or close every fold of your P&L at once. A fold hides the smaller lines between two big lines. The button sits in the header of the Line column, above the line names.

GMV and each subtotal can fold the lines under it. The subtotals are Gross Revenue, Net Revenue, CM1, CM2, CM3 and EBITDA. Click the small arrow before one of them to show or hide its lines. For example, the arrow before Net Revenue shows Net Orders, Net AOV, COGS and COGS %.

Folded all the way, the P&L becomes a short summary. You see GMV, Gross Revenue and Net Revenue, then CM1, CM2, CM3 and EBITDA with their percentages. Each margin keeps its percentage line, like CM1 %, right under it. EBITDA has nothing under it, so it has no fold.

The button reads Expand all while every fold is closed, and Collapse all once one is open. On your first visit, every fold is closed. After that, nouz remembers which folds you left open, in this browser. Folding only hides lines, so no number changes.

Do not mix this up with the arrow after a line's name. That one opens a breakdown of the line, like each payment method under Transaction Costs.
