Browser extensions and user scripts have shown that there are lots of useful ways to modify websites, ranging from blocking ads to adding entire new features to Gmail.
Wildcard is a platform that empowers anyone to build browser extensions and modify websites to meet their own specific needs.
Wildcard shows a simplified view of the data in a web page as a familiar table view. People can directly manipulate the table to sort/filter content, add annotations, and even use spreadsheet-style formulas to pull in data from other websites. The key idea is that a table view is simple and easy to work with, but surprisingly powerful in the range of modifications it can support.
