I'd like to start a separate discussion on the issue "no spamnerd" brought up in the 6.0 wishlist topic.
In brief, the issue is that TeamCity Overview page does not serve its "overview" purpose well when the TeamCity installation grows large and has many projects, each with own branches, etc.
Possible approaches to the issue can vary from as complex as portlet-like widget solution which is customizable per-user to as simple as ability to tag build configurations + easily switch the view to display only specifically tagged ones.
Related ideas from the tracker:
TW-705 - Allow projects to be grouped into categories and viewed/managed by these groupings
TW-11124 - Grid view for projects list page to fit more on the page without needing to scroll
Could you describe what do you want from the Overview/"Home" TeamCity page mentioning the root needs that you have? If you have ideas on implementation, please share them but do not forget to describe what pains you need to relieve or what insight to get with the solution.
