With the Text Tool, you can add rich text to your image. Drag to make a rectangle which will contain your text. You can set the initial font of the text in the options bar (its initial color will be the current primary color), but you will be able to change the text, fonts, and colors used in the Inspector after you have drawn the text vector. You can assign a non-transparent background color to a text vector to make it render with sub-pixel antialiasing.
