The best thing so far is threaded replies so you can see who replied to who... I still can't understand how any platform wouldn't have that? Anyhow so I have the latest SEM installed in a new area and am about to upgrade my 2020.2.1 larger system to latest version. I got some conflicting info at first and opened a case because some docs said I could upgrade directly to 2020.4.1 and another doc said I had to upgrade to a version in between first. Then after I pointed to the main doc that says 2020.2.1 -> 2020.4.1 support said go for it. Suffice it to say that didn't exactly give me a warm and fuzzy feeling.
