With this update for DarkPaint, some bugs have been fixed, the ability to change the resolution of the project, save and load a set of materials has been added. The Unndo / Redo function can now be turned off at will.
When loading a normal map into a material set, an additional window now opens for selecting an image of a height map.

There are many plans for the development of this add-on, but very little time.
sorry...
