It looks like this was rejected over a year ago, but now that this feature is appearing in other frameworks it would be nice to reconsider.

Each tab having its own history is core to making things work like it would in a native app. It is just so sloppy when a user loses their state going between tabs.

You are able to do this with the ionic tabtrip http://ionicframework.com/docs/api/directive/ionTab/ so i would hope kendo can too.
