No, or at least I haven't found one. I was recently forced to upgrade from 14.04 and tried the default configuration in 18.04 (clean install) for a while before I gave up and installed Unity -- which, thankfully, is in the package manager. That at least got me back to the point where I could configure things critical to my workflow like having a 3x3 workspace switcher. The system has fought me every step of the way though -- especially with things like global hotkeys which have about half a dozen different places they can be configured and it's completely inconsistent what works where. I've literally spent weeks trying to get back to the level of usability I had on my 14.04 setup -- compiling old/patched versions of software from source because the "improved" versions removed features I depend on or otherwise fucked up the interface (I cannot understand why anyone thought removing typeahead from Nautilus was a good idea!), trying every damned thing I can think of to debug the global hotkey problems (still can't get IME switching to work right reliably... it works for a while after I fiddle with it then just stops working and I have no clue why), and just generally having a bad time.
