I'm sure this was already discussed and fixed in the past, but when extracting more than one archives (or add them later to queue), you have to wait until each extraction is finished until DO asks for password.
I would like to enter all passes at the beginning (or when adding to running queue), so I that can make in coffee in the meantime .
WinRAR and 7-zip both accept passwords via command line. WinRAR also has a small password list organizer. If you need to work with longer lists you could use tools like UnRarIt or ExtractItAll.
I know that, but DO supports archives, so asking immediately for a password when another extraction is still in progress or queue is a useful option for everyone not using an additional software like WinRAR.
