Geometric shapes, text and notes
I am from the exact area and I have some difficulties with the application.
In geometric shapes, you can add: arrow, trapezoid. - Place the option on the geometric shapes to fill the shape and line types (dotted, dashes, etc.).
For text, add other fonts by filling in the font and shading the letters. (It would be fantastic)
Improvement when writing with reduced magnification, the line appears "cut at several points".
Place a fixed option in the place bar as if it were some annotation images to write on top.
