6:05Dive straight into undo / redo functionality for UpdateAndRenderEditor(), introducing in_game_edit struct, IsEmpty(), UndoAvailable() and RedoAvailable()

16:57Introduce align_point_edit as one of the types for in_game_edit to contain

19:51Introduce EditAlignPoint() and AlignPointFromAssetAndIndex() for AssetEditor() to call

25:24Introduce ApplyEditChange() as a dual-purpose undo / redo function for UpdateAndRenderEditor() to call

31:08Introduce IsDirty(), and separate Undo() and Redo() functions for UpdateAndRenderEditor() to use in the "REVERT" case

38:19Create handmade_dev_ui.cpp and .h to separate the game, editor and debug system's UI
