A terminal with history, a Go-colored code block, a log viewer that follows, a hex viewer, a memory map, a JSON tree, a line diff, a GAME OVER crash screen, an FPS meter, profiler bars, breakpoints, variables, command history, a shortcut list, a debug grid, a pixel editor that exports string art, a palette editor, a sprite sheet, a glyph map and a 6502 register view. layout.ScrollArea takes Follow, and ChatLog now uses it. data.TreeNode takes a Value drawn in its Slot. pixel gains Has, and Sprite.Art writes MustSprite art. pixel.Editor takes the caller's value at each input event, so a value changed between frames is never typed onto.
