A Rails grid plugin to create grids with sorting, pagination, and filters generated automatically based on column types. The contents of the cell are up for the developer, just like one does when rendering a collection via a simple table. WiceGrid automates implementation of filters, ordering, paginations, CSV export, and so on. Ruby blocks provide an elegant means for this.

Automatically makes your Rails app loading content in the background via ajax. Works by turning all internal links into ajax links that trigger an update of the page's content area. Also form submissions are automatically turned into ajax requests. Uses the html5 history interface for changing the url and making the browser's back and forward buttons working with ajax. Falls back to a hash based approach for browsers without the history interface (like Internet Explorer <10). Transparently handles redirects and supports flash messages and page titles. Requires Ruby 1.9 and the asset pipeline.
