Hi, I have 3 good news:) Undo / Redo. I covered most of actions with undo/redo functional, it remembers last 10 actions. The intricate processes of drawing (polygon, paddle, arch) remained intact, but in the editing mode everything works. Import / Export effects. There are two buttons on top of Presets tab for saving and loading effect libraries. The default library is located at the root of the DPS folder (default.dpf). If you save your library over, it will be loaded every time you restart. Preview scaling. In the bottom right corner appeared a slider resizing previews, the smaller the size, the more of them will be placed on the screen.
