When adding text to a sketch, I often need to find a font and font size that fits properly and looks like what I need. To do this, I have to keep going back and forth between the font chooser and the sketch because it doesn't update the sketch until I  press OK. This is a very time consuming process as I have to reselect the Font button to bring up the Choose Font dialog box every time I need to change to a different font or change the size. I think an extremely useful enhancement would be to allow the update of the underlaying sketch as as changes are made while the Choose Font box is still active. Maybe put an Apply button on the dialog box and keep it open until OK or Cancel is pressed.
