Hello
French player here
Copy/pasting the introduction since i saw that thread after my first post. (yeah, my bad)
I'm a rather new player in the game (bought it a few weeks ago) and since then, i mostly played with the submarine editor. In fact, i played only a few hours on either multi or single player, and over 100 hours on the editor or testing my submarines

My favorite submarine has multiple functions, like a dual purpose shuttle that can either be manned or remote controled (and with slave controls when docked, adding her engine power and ballast to the main sub), security cameras linked to a single periscope which change view on mouse click ...
Basically i like to think "wow this could be cool / fun, i'll try to do it !"
I'm currently working on vocal commands, with a WiFi linked to chat. I can do some nice things like turning lights on or off by a simple vocal input.
