I started doing some work on the version of D&D Manager for 4th edition D&D as a separate program as there are a fair few changes from 3.5 edition. But although I will be contributing and working on it a bit I don’t have time to do the whole project on my own (or it will take a long time – like a year or so). So if you’re interested in helping let me know by email.
The code is viewable online at: dd-manager.svn.sourceforge.net/viewvc/dd-manager/4-ed/ and it can (probably) be downloaded if you have svn installed with:
svn co http://dd-manager.svn.sourceforge.net/svnroot/dd-manager/4-ed/ dd-manager-4ed
