I request you to develop the configurator for OS 10.4 too. I don't want to be forced to buy the new operating system. I don't mind if this configurator lacks some features the configurator for Leopard contains.

Sorry, but we had to move to Leopard-only, and probably Intel-only support.
Supporting numerous platforms takes a lot of time, that we'd rather spend on polishing and making new features instead.

On your website I can read under system requirements:
PC with installed OS Windows XP or Vista, with a USB 1.1 (or better 2.0) port; Mac OS X 10.4.8 or higher.
And I have relied on that informations for all the time! I understand that it is too much work to develop a configurator for all the different platforms an OSs but you should at least offer a Configurator with basic features for OS 10.4.8-10.4.11. I think and I hope that should be possible without enormous additional work. What do you think about my request?
