Panelet

Panelet is a term that can refer to a small pane or panel, but its exact meaning is not standardized and its use varies by field and historical period. In general, it denotes a diminutive component that resembles a pane or panel within a larger structure or system.

In architecture and glasswork, a panelet may describe a small pane of glass within a window or door, or a decorative element composed of several small panes arranged in a grid. Such arrangements are common in historical window designs, including lattices and casements where multiple panes come together to form a larger field of glass.

In modern computing and user interface design, panelet is sometimes used informally to describe a compact, self-contained panel or widget within a larger window or dashboard. Panelets in this sense are intended to display concise information or offer quick controls, and they may be designed to be movable, resizable, or collapsible to save screen space.

The term is relatively rare in technical writing and is not a widely standardized term in contemporary glossaries. When encountered, panelet should be interpreted from context, with attention to whether it refers to a physical glass pane, a decorative architectural element, or a small modular UI component.
