@srpearce This tool was ported from Java to JS using GWT. The problems to solve are specified in Java code directly. 7.00x decided to use 5 out of 13 types of problems. Some Java GWT code was written to interface with these. All of this to say that without additional code writing and recompiling, only 5 types of problems are accessible. And to my knowledge, only one course uses Genex, 7.00x.
