This are some of my own suggestions, after I spent five hours in office reading about your installation guide and help resources:
Make Synaptic the default package manager
Provide appropriate IDEs (apart from Bluefish, NetBeans and Eclipse)
Provide compiler support for the Google GO, Prolog, Scheme (apart from Clojure) and the ML language (to be supported with Poly/ML)
Update CUPS so that it can handle the wireless Canon MG3670 colour inkjet printer
Update Internet connection support by adding the Huawei E1550 3G USB modem into the devices list.
