MyPaint is a drawing program that specializes in creating drawings from scratch. The program simulates real drawing tools (brush, pencil, etc.) and allows you to create "digital" works.
However, despite the fact that the program is well suited for design and fine arts, it is not a full-fledged graphic editor. In order to overlay any shapes or crop a picture, you need to use other tools, such as GIMP.
The MyPaint interface has been deliberately made minimalist and fully controlled through hotkey combinations. The idea of the program is to give the user the opportunity to draw without being distracted by anything.
Thus, users usually work on their canvas without any menus being displayed. In order to change the tool or adjust its parameters, you need to click on the key combination to display the dialog, menu, color selector, etc. After they are used, they disappear from the screen again. However, although many artists prefer this approach, others have fixed the dialogues in plain sight. Try different methods to choose the best for yourself.
Key combinations are selected so that you can use them with your left hand while your right hand is occupied by the mouse. These combinations are easy to change and customize.
The program is perfect for artists. Its interface is very clean and pleasant to use. Another big plus is the lack of payment for use.
