Just playing around with UI5 found out that i currently miss a lighweight notifier widget.
UI5 depends on jQuery and there a countless community plugins that will do such a job.
To make live easier just googling for best jquery notifier plugins and i found some useful blogs with pros ans cons on widely used libraries.
The full blog usin (noty) including example code can be found here
