Hello everyone, I wanted to put a new feature blueprint for which I just opened a PR on your radar:
https://github.com/apache/trafficcontrol/pull/4819 The tl;dr is that it's a blueprint for adding Tags to Traffic Ops, which I think is a pretty long-requested - and even worked-around - feature. Tags are simple alphanumeric strings with no implied meaning that can be applied to things like servers and Delivery Services (see blueprint for full list). Should be a pretty non-invasive change if you don't care about them, just a new optional object property in a few places.
