An architectural covering may include an adjustment member configured and positioned to adjust friction affecting movement of the covering. The adjustment member may be manipulated to increase friction in the architectural covering so a covering member (e.g., a panel) of the architectural covering does not move as freely as it would without the increased friction, yet the covering member nonetheless remains simple to operate. The additional friction may be effective to inhibit the covering member from moving across an associated architectural feature on its own without a user's input.
