I'm a keyboard guy.
I backed up my DOpus9 settings and then intentionally uninstalled DOpus 9 before installing DOpus 10. I'm a true computer geek in the sense that I'd like to see all the new stuff and not be held back by my old settings and preferences.
I installed DOpus10 with Explorer replacement mode turned on. Default lister is dual pane with folder view (same as freshly-installed default) but with each pane having two tabs. Left pane tabs are C: and AddOns and right are D: and AddOns. However, since DOpus10 installation, Windows+E always makes the left pane have only one tab and it displays My Computer instead of C:. The right pane is just fine.
