David Sarnowski's post in [Feature Release in Version 10.14] Restore Quick Switcher (CMD+ J) was marked as the answer
This really needs to be prioritized. I have seen so many other little features added into the new version that are unimportant ahead of this. This is central to so many workflows for people. If this is in the Coming Soon area, I expect it in the next release. If this is 4 months out, please take it off the Coming Soon and stop teasing.
