I'm brand new to DOpus, and currently evaluating the v11 beta, so please forgive me if this feature already exists and I simply haven't discovered it yet (though I have rather exhaustively searched through preferences). In Windows Explorer (I'm on v7 Ultimate, 64-bit), if I have two explorer windows open, and if I have clicked on various folders and subfolders to generate a history in each, I have only to hover my mouse over either window (with active focus or without focus) and my mouse buttons for forward / back will traverse my folder history in both cases. In other words, mouse forward and back buttons will work on whichever explorer window my mouse pointer is hovering over: it doesn't matter if it is the "active" window (has focus) or not.
I would love to see this as an option for DOpus when using dual pane listers (which is my default style). It's quite convenient to be able to quickly point and shoot with the mouse when I want to traverse history in either pane. As it stands now, I have to either click on a folder in the inactive pane, or press the Tab key to switch pane focus--both of which involve one extra motion. Yes, I know, it's seemingly trivial, but it's a feature I'd grown accustomed to when working with two explorer windows and I'd really like to be able to replicate it in DOpus. It could be an option in Preferences ("Mouse buttons work on whichever pane the mouse pointer is hovering over").
Come to think of it, it would also be very handy (as part of this feature) if the mouse wheel would scroll through folders/files in whichever pane the pointer is hovering over (regardless of which is the active pane)--that's something that not even windows explorer does.
Ah, I see DOpus does do this already. So in effect (at least on my system, with my hardware), dual-paned DO performs just the opposite of Windows Explorer (x2): it will scroll whatever list the mouse pointer hovers over, but will only apply the mouse's back/forward buttons to the active pane; win explorer, on the other hand, will traverse the folders in any window that the mouse is hovering over using the back/forward buttons, but will only scroll the active explorer window's listing when employing the scroll wheel.
So my original feature suggestions stands. That will give us the best of both worlds.
Opus really works the same way as Explorer does, since two separate Opus windows behave the same as two separate Explorer windows, and you can't have dual file displays in Explorer.
Making back/forward buttons go to the file display under the mouse in a dual-display window may still make sense, though (as long as we can reliably detect if the back button came from a mouse or keyboard, since it would be really bad if the keyboard behaviour changed).
Understood. It would just be really convenient to allow ALL mouse controls to operate on whichever pane the mouse pointer is currently hovering over. Count it as yet another feature DO would have that Explorer (and other file managers, for that matter) lack.
