Notes:
- Errors that prevented me from testing with Localization package version 1.0.0:
-- “…error CS0104: 'TreeView' is an ambiguous reference between 'UnityEditor.IMGUI.Controls.TreeView' and 'UnityEngine.UIElements.TreeView'“
-- “…error CS0246: The type or namespace name 'RowGUIArgs' could not be found (are you missing a using directive or an assembly reference?)”
-- “…error CS0122: 'DragAndDropArgs' is inaccessible due to its protection level”
