One thing that is missing in ZK is a complete set of notification components:

• Info notification;
• Warning notification;
• Error Notification;
• Try Notification;

for each component, I would expect to find appropriate graphics and all the following:

• Possibility to stop/interrupt the execution;
• Position (absolute or relative to another component);
• Content: plain text or html;
• Delay or click to hide;

As far as I know, ZK has only Error Notification Clients.wrongValue(Component comp, String msg), but this is very limited ... would be nice to have a complete set of notification components, like Vaadin Web Framework (sorry for the comparison), in the next version of ZK!

thank you very much!
