SUMMARY
Could you please add a command-line argument to start dolphin maximized? (e.g. -m or --maximized)

This would allow users to create more useful shortcuts for dolphin. One example would be using dolphin for a media center as described here: https://unix.stackexchange.com/a/582832/233262

Additional view options for dolphin would also be useful. As of version 18.08, which is the version that's currently packaged on latest Debian stable, the only view option when starting from command line is --split which starts dolphin with a split view.

I previously asked about the same thing for a fullscreen mode here: https://bugs.kde.org/show_bug.cgi?id=420851

(And in case anybody needs this feature now: a temporary/suboptimal workaround would be to use wmctrl as described at the link above.)
