I'm working on an admin module and I'm using the build in notification system for messages, errors and warnings, which works great. Some of my forms are handled by ajax however, and it would be nice if there was a javascript equivalent of $page->message("hi there"), like there is for the SystemNotifications module. (Which works like Notifications.message("Message to send").) I currently have a custom notification system for ajax in place, but it would be nice if I could use something purely PW. Can this be done?
