when using the select operations (select, unselect, select all), the respective list view will not be activated. As a followup, several buttons in the UI will not be active to start operations. I am not sure whether this is intentional or not, I just find it counter intuitive. If I select all files, the next operation I choose (e.g. deletion) should operate on this selection and not on a selection in the other list view.
Setup: WinSCP 5.9.4, Commander View, Windows 10
