众所周知
Mathematica的变量管理还是挺缺失的，所以使用一些代码来添加变量管理：
CreateWindow[ PaletteNotebook[ DynamicModule[{initPlot, arrays, display}, Column[{Dynamic[ Grid[With[{expr = ToExpression@#}, {PasteButton[RawBoxes[#]], Head[expr], Dimensions[expr], ByteCount[expr], Button[Style["Display", 10], CreateWindow@ PaletteNotebook[ Pane[TableForm@expr, 400 {1, 1/GoldenRatio}, Scrollbars -> True, AppearanceElements -> None], WindowTitle -> #, WindowMargins -> Automatic, WindowSize -> 400 {1, 1/GoldenRatio}]], Button[Style["Clear", 10], ClearAll@#], Button[Style["Remove", 10], Remove@#]}] & /@ arrays[], Alignment -> Left], UpdateInterval -> 1, TrackedSymbols -> Full], Button["Prepare plot", initPlot[], Method -> "Queued", ImageSize -> CurrentValue@"DefaultButtonSize"]}], Initialization :> (arrays[] := Select[Names["Global`*"], Head[ToExpression[#]] === List &]; initPlot[] := CreateDialog[ DynamicModule[{names = 1, picked}, Column[{TogglerBar[ Dynamic[picked, Which[Length[#] <= 2, picked = #, True, picked = #[[-2 ;;]]] &], arrays[]], Button["Plot", DialogReturn[]; CreateDocument@ ListPlot@ If[Length[picked] == 1, ToExpression@First@picked, Transpose[ToExpression /@ picked]];, Enabled -> Dynamic[Length[picked] > 0], Method -> "Queued"]}]], Modal -> True])], WindowTitle -> "Global Lists", WindowSize -> {Fit, Fit}, WindowElements -> {"VerticalScrollBar"}]]
