Sorry for the delay in developing apps. My computer is in a very fragile state right now. It will not start up at all. This happened after trying to install Ubuntu 7.04 which was unsuccessful. In fact, I am typing right now under the Ubuntu Live CD which ironically, does work. My system will be back up and running with the release of Fedora 7 (Rawhide) on May 31st.
I am also developing an application parallel to PAFL, iProto, which will be a simple and powerful prototyping application available for download at PorTools.com in about a month.
By the way, did I ever tell you how the domain name came to be? PorTools was intentionally meant to stand for Portal Tools(PorTools), but that did not come around. Then I developed PAFL and recently realized that PorTools can be Portable Tools as well! What a strange coincidence!
