Tree/Semi-Flat view in File Display window (with details view columns)

We have Flat View (w/ & w/o folders) for the File Display pane and that is great.

I am requesting a 3rd form of Flat View.

Basically it shows the sub-folder tree, with expansion and collapsing, but lets me select items in multiple folders simultaneously (like Flat view does). I would also have multiple (maybe all folders) expanded simultaneously.

Also, in the tree or semi-flat view, I would see the Size, Type, Modified, etc columns. I am thinking that the Name column would have the +/- buttons and indent the names as needed (i.e. the tree).

That way I can see the hierarchy, ignore the parts of the hierarchy I don't want, and interact with this as if I was in normal Flat View.

If this is already part of DOpus and I just don't know about it (because I know only 15-25% of what DOpus does; it is expansive), please let me know. My normal Lister is Folder Tree on the left and 2 File Displays on top of each other on the right.

Thank you

Something like this is on the "to do" list for a future version, but it's fairly complicated because of the existing design, so it's not something we'll be adding soon unfortunately.

OK, thanks
