There are still a lot of things to do, patches are welcome

* Calculation of the height of the textfields, so we can center them
  vertically

* Help functions
	Maybe balloon help

* Use some predefined options for different types of label-sheets

* Use a pipe for the preview function

* Use different media (/etc/papersize for debian)

* Read the text from a cddb 
	A look at cd-labelgen may help

* A canvas window to move the objects interactively

* Allow for two identical labels
