Oh, that is sweet. I like it! I'm with Mr. Darwin - this could finally convert me.
I currently have licenses for Directory Opus, Total Commander, and XYPlorer (Lifetime Lic.). I have never used TC full-time though I have had it longer than any other. The UI is just different enough and I never took the time to master it. DOpus is my everyday file explorer currently, but that could now change. I do like XYPlorer but dual pane is a big plus for me, and not having it was a big minus IMO, at least for my use. I do a lot of file copying and moving and it is definitely much simpler with the dual pane.
