The differences are small, so I don't really mind having the layout as it is.
I haven't found the command for the Info button. I know the Enigma2 key number is 358, but I couldn't find one for Enigma1.
The command for the screenshot is Code: http://<dreambox_ip_address>/body?mode=controlScreenShot The resulting screenshot image is located at Code: http://<dreambox_ip_address>/root/tmp/screenshot.bmp I did a quick test and used wget to download the screenshot image, and it works.

You may already have seen these, but here's a couple of links for web interface commands: http://radiovibrations.com/dreambox/webif.htm and a Wiki in German: http://dream.reichholf.net/wiki/Webinterface_Befehle
It would be cool to have some of the EPG/Timer commands etc. For example, you could retrieve the EPG and display it in a QML WebView (or use your own display UI), and allow setting of a record timer without needing to see the TV.
