The SlateKit Shell browser features a sliding-drawer user-interface with side-tab support, search suggestion and highlight via LocalStorage, and custom event binding. The browser is licensed under the Apache 2.0 license.
This browser is part of the larger SlateKit.org project to provide an open-source tablet user-experience building kit. SlateKit comes down to a set of Qt-based components to run atop Android.
