Blinking icons! We currently use maps with background or our buildings with the device icons in each building. This can get a little cluttered. It would be nice that if a device status was warning or down that the icon would blink - catching the viewer's eye.
The ability to include custom poller information in the labels for these devices. For example, if you have a UPS on the map then be able to have the label show values such as load, capacity, etc. Very useful for this as well as other things....
The ability to have nested maps show as they do when you do a preview. Currently when you design a map and lay it out as you want it then have it as a nested map the layout changes to just the map and nodes below it.
The ability to have a page with multiple nodes detail segments displayed on one page.
