That would be useful for loading Claws Mail on system start. At the same time, launching Claws Mail without options would open its window as usual.
Are you aware that the Notification plugin's SystrayIcon module already has an option to 'Hide at start-up'?

I'm away from my home machine right now, but am I right that this option makes Claws Mail always start minimized to tray? As far as I remember, it is so. But if I start Claws Mail manually, I want to get to its window immediately. Starting it minimized to tray for me only makes sense on the system start-up. And why would I want to start it manually if it is already launched on system start-up? Because you may want to exit the program for different reasons. It may not be an issue for a lot of users, but if it's not too much trouble implementing it as a CLI key, I would be glad to see it.
Another question is, why do you want it to be started in a minimised state if it is started at on system start?

An analogy: if you have auto mounting enabled (so that inserted flash drive is mounted on system start-up), does it mean that you want this flash drive opened in your file manager when the system is loaded? I do not, I just want it mounted.
