Missing Element/Tool

Though I enjoy using the Pixlr, one very important element is now missing from the current program—the history/brush/eraser. Without this tool the program is useless. Yet the eraser function is available on line. Why is it not included in the purchased version of Pixlr? Is this an oversight? If so, it should be made available to purchasers of the program at no further cost. Overall, the program has great promise, but this missing element keeps it from being truly complete. Please fix this problem immediately to make the program worthwhile..
