The only way to move a drawing is by using the rectangular selection, making a selection with it and moving it with Shift and mouse drag. There is no automated way to centralize drawings currently.
Ok, also i noticed that in the pencil tool brushes like Dot, circle, etc can change colour but there are some brushes Like star, Hline etc (i am talking about the brushes at the end) that only paint black. How can i change them?
By default, the brushes are using their original colors, since it is possible to save brushes with color. To change their color, you need to set the "Brush color from" option to 100.
