I am enjoying the new MacOS Mojave, except for the occasional System screen freezes that is. I am sure this will be fixed in 10.14.1, due out anytime. One thing that has always annoyed me is the macOS puts my screenshots on the Desktop. If you are trying to keep the Desktop reasonably clear, this is not helpful. However, in Mojave you can choose other locations for the OS to save your screenshots. This article explains how to do that, it might be helpful to you.
