@gyoshev the only real issue, thus far is that there is the notion of dismissible notification with a dedicated class name. We could open a new FR for KendoUI and the flavours for that

The rest should be pretty straightforward.

Isn't that something specific to the bootstrap layout? I could not follow how this affects the Kendo UI components, i.e. the notification styling.

[joneff]

It doesn't affect them really. It just seems like a nice idea to have this class name, so we can provide extra padding on the far side of notification. The difference may be visible in multiline notifications, but that's about it.
