Sketch: be able to change color and fontsize for text(s) on a drawn object

[Albinahmetaj]

A user in our municipality utilized the Sketch plugin to draw a line object and enabled the 'Show text on objects' switch in the Sketch settings.

When any type of layer with a white background is used in combination with text on the drawn object, it sometimes becomes visually difficult to read the text.

A suggested solution would be to add a color picker, similar to the one in the Print plugin, along with a slider to adjust the font size, just as we currently do to change the size of a point object. Maybe add this inside the sketch settings tab?
