I want to send OpenInMode command with a Highlighted file entry. I can open only one file, and there are no problems when we have no selection (we get auto-selected the active entry, I guess) or we have selected only a single file. But when we have a selection, we are still able to change (using keyboard up/down arrows) the single active entry (the highlight), but we don't know was this "selection down" (the last selection is "pdfe.SelectedFiles(pdfe.SelectedFiles.Count)") or "selection up" (then the last selection is "pdfe.SelectedFiles(0)"), and we need to choose to open a single entry (without loosing the selection) and the choice criteria has to be intuitively clear. That's why it's useful to get CurrentSelected, or LastActive, or the Highlighted entry.
The same trick is in Total Commander - you can select many entries, but by default you open only the active one, which can be not selected at all.
What do you think?
