I can appreciate exactly what you are saying. I had a similar feeling about Walling. The potential usefulness is there. And for a while, development was brisk. Then, as you say, it died down to almost nothing. From experience, I've learned not to trust new stewardship of applications. They always promise continued development, but rarely follow through -- Bending Spoons and Evernote a rare exception. But I do hope Walling is also an exception.
