The SmartConsole capabilities are separated from CDT and it is not a GUI for CDT. It is developed by the same team to make sure we learn from the CDT development, but it has much higher focus on usability, and hopefully it can be used without any learning effort.
As @PhoneBoy wrote, we will continue to bring new capabilities to SmartConsole, but I expect CDT to stay with us for a very long time because frankly, it is much more powerful. We will definitely continue to develop and support both options.
The cluster suggestion is a high priority for us, but unfortunately it will probably only be available towards the end of 2021. The reason - we want to make the UX perfect, and it requires some more research and usability trials. If you are interested to contribute this effort, share your thoughts and even try out early developments, we would love to contact you for an open discussion.
