It appears that I cannot help myself. I told to myself (Since you are updating KawigiEdit anyway, why not add the stuff you have always wanted it to have?). And there we go...
This update is cool mainly because you can now temporarily disable test cases. This can be very useful during a match when there are 7 cases. One test case is wrong. But debugging the test case is difficult because the other 6 cases cause you trouble. I took this idea from watching Petr's screencast for SRM 550. He uses CHelper, which I am sure is a great plugin, but it is only for Java coders.
