Generic list inside editor window

Rotorz ReorderableList

Reorderable List Control for Unity

Items from generic lists can be presented using custom item drawers. A custom item drawer is essentially a delegate which is called to draw each list item. The generic list adaptor can be subclassed instead if items of varying heights are needed (see Custom list adaptor).

Tip
Consider using serialized properties instead if undo/redo support is needed.
