When using Sencha Ext-JS, I used the popup notifications a lot! It was compact, easy to customize and sort of looked like this:
Ext.create('widget.uxNotification', {
title: 'Invalid Phone #!',
closable: false,
position: 'b',
iconCls: 'ux-notification-icon-error',
html: 'The phone # has to be 10 digits. Try again',
slideBackDuration: 500,
autoCloseDelay: 3500,
slideInAnimation: 'bounceOut',
slideBackAnimation: 'easeIn'
}).show();
For you Javascript experts, wonder how hard it would be to duplicate this to use in Aware. (I can give up the animation), The fact I can change the icons from errors, to warnings, to info, control which buttons were displayed, etc. let me create a rich UI for my end users.
