Navigation the user chooses, not the designerRequested by users
Three modes, switchable: fully expanded; a narrow icon rail where hovering a group icon opens its links in an overlay; and fully hidden, revealed by moving to the left edge and dismissed by moving away. Items can be pinned above the groups. The groups themselves collapse.
The links and their names did not change. What changed is that a flat undifferentiated list of twenty-plus modules became collapsible groups, and that hiding the menu stopped being a trap: the previous behaviour opened on hover but required a click to put away.
Three modes because the feedback sessions produced three genuinely different working styles — people who want the menu permanently open, people who want a thin rail, people who want the screen entirely to themselves. Cheap to build, and it ends an argument that has no correct answer.
Considered instead
Picking one mode as the right one for everybody. It is the tidier design decision and it is wrong here — the disagreement was real, and the cost of honouring it was low.
Ties to Rule 1
Every mode is an answer to the same question the panel asks: how much of the screen belongs to the data. Here the user answers it instead of us.
