The customization is endless for your views. Create a Group and assign the nodes you want to view to that group. Create a map with Network Atlas and add the group to the map. Add the map to your NOC view or default screen, aka where ever you want to be able to view these nodes and you have a specific view for those nodes. BTW, you can create a new view too that only has these specific nodes and/or groups. Go to your admin console for NPM and just browse around and see what you are able to customize. It can get very much more detailed depending upon what you want to be able to view from adding tooltips to nested maps to endless possibilities...

When you create tabs and want to remove something from a tab layout, don't hit the 'X', DON'T HIT THE X I SAY. That will remove it from your "Available Items". You can re-create it, but it will remove it from every user that you have that applied to. You will then have to find out who had it, most likely you will get calls like I did. You will then have to apply it back to every tab. The same is said with views. Make sure what you are removing before you do it. When you make a change, it is applied to every user that has that view. It can get confusing, but you will get the hang of it after breaking a few things. LOL
