Ah that's fine, this is explicitly not a tool for the masses. The problem I had with tools like the ones you describe are that either they just use string matching, or the selectors they generate are particularly brittle (e.g. incorporating randomised class names, like you mentioned elsewhere). Given that there wasn't really an alternative to scraping for me, I wanted to at least be able to pick selectors myself that were less likely to break with minor changes. Then I figured there might be more people who know CSS and have the same desires, hence my sharing it here :)
