I like the tree view in the Monitoring Dashboard and BizTalk Group Dashboard, but even with just a few applications it gets reduced in size to something that is less useful because the zoom out required to see everything. There ends up being alot of white space that could be better used in my opinion. I'd like the option to switch the vertical tree to a horizontal tree like in File Explorer. This would allow the screen to handle a multitude of applications as the user could simply scroll down to review them. The screen width seems like it would be wide enough to accommodate the 4 or 5 levels of depth required for applications or other aspects of monitoring. To be sure you would still need to zoom out to get a full view of the tree, but I think the option of a horizontal format would be more intuitive to navigate and easier on the eyes.
