The tool certainly still has a lot of shortcomings, but you can see that the people behind it are responsive to requests for changes and are actively working on them. I bought Tier 3 and look into it from time to time. I have made a few comments and I see that quickly my comments are implemented and the tool gets new functionalities that work well. I think it is worth giving them a chance. Write what you don't like and see how keywordly is positively changing.
