Hi,
I have been developing web (js/RoR) and iOS applications for the last few years and now I start to get interested in system 7 C++ development.
In fact, I installed system 7 on my well upgraded 9500 and I think I will never go back to 9 again. System 7 on that machine is so fast, such a great user experience! Sometimes I even feel that my intel iMac is quite slow after using the 9500.
I use 7.6.1 and I feel that some modern applications/utilities are missing and could be done without much pain (maybe I'm wrong...). So, I would like to start developing some of them on my free time and make them open source of course.
I am thinking about connected applications such as a twitter client, gmail client, or a cool control panel like a dock to replace the default mac launcher. In fact, I think that plenty of small iOS/mobile applications could be made for system 7.
My ultimate dream would be to have a lightweight webkit component working under system 7 to build apps on top of it... this is just a dream at the moment
