What are some of the more creative ways you use Custom Properties?

Oh man, these are core foundation for the entire framework. I have not many of them, but I do believe that 99% of stuff can be automated just be using custom properties AND ... it is easy to do from the user perspective, which leads to much fewer mistakes and more robust, reliable and consistent monitoring environment

For example:

• SiteID. Once picked, we will then display full information about particular site on the node page + we will automatically adjust latency + we will automatically place node on the world map + we will automatically calculate dependencies
• Environment and Impact are two custom properties that we use to filter out any alerting noise. We only send alerts in for production machines and/or high impact server.
• Almost any possible threshold has been implemented with custom properties being an overrides, such as overrides for Disk Queue Length, Disk Latency, Interface Discards, Interface Errors, CPU and many more. Many overrides are already there as part of standard Orion platform, but I found that we always in need for more granularity and flexibility and Custom Properties is a Magic
• I also use them for reminders, for muting mechanisms, for notification purpose, and on and on
• Many of them we use just for information - notes, contacts, phone numbers, warranty, PO, etc
• And obviously this one tells it all

If I were to unswer what is the gratest invention on the XXI century - I would give my vote to Custom Properties within SolarWinds

SiteID. Once picked, we will then display full information about particular site on the node page + we will automatically adjust latency + we will automatically place node on the world map + we will automatically calculate dependencies

What do you mean by this specifically?  Do you have a custom view that displays metrics of each site?  I have wanted to do something similar to make 'Site Views', but wasn't sure on the correct approach.

Yes, I do. I have reports designed in Report Writer which will lookup for Site ID in my Auxiliary table and will then output all address details on Node's page dynamically. This is shown in bonus section here
