Lists, tables, trees, grids, inventories and records in data/. Outline and GridView build on ui.List: ui.Outline strokes its arrows and ui.GridView spaces and tints items. The pixel theme keeps MyGo's row highlights clear so scrolled rows stay on whole dots; off lists take a veil against the wheel. Adds Canvas.Silhouette, SwitchOptions Label and exports Rarity.Slot.
