[2026.1] Advanced Course and Depth Control

Allows for better course and depth control with the help of hotkeys. The following is already implemented: More granular course adjustments If you hold down the shift key, clicking the Course Change 90° button will initiate a 45° turn instead. Holding down the control key will result in a 5° turn. And finally, if you hold down both shift and control at the same time, the course will be adjusted by 1°. Hotkeys for course changes You can now use the arrow keys to adjust your course. Left arrow for 90° port, right arrow for 90° starboard, up arrow for rudder amidships, and down arrow for a 180° course change. These work in conjunction with the course adjustment hotkeys, so shift + left arrow will change your course by 45° port, and so on. You can disable these hotkeys by pressing control + capslock. This will act as a toggle. Hotkeys for depth changes While holding the control key, press F to increase your depth by 5m. Holding shift alongside control will change that to 1m. Pressing R instead of F will likewise decrease your depth. Holding control and pressing both R and F will keep the current depth. Increasing depth while on the surface will flood the tanks, and going to 0 depth will blow them. Holding control and pressing P will put you to periscope depth, while holding control and shift and pressing P will set your depth to 20m. Holding control and pressing C will initiate Crash Dive when you're surfaced, or initiate a dive to maximum depth when you're submerged. This is fully save game compatible and will uninstall cleanly. Planned Features (currently not being actively worked on, sorry!) I want to add an UI element, like a text box, to the compass that allows you to enter a specific course. That way you could enter "313. 3" into the compass using your keyboard to set a precise course to 313. 3°. I'm thinking of implementing a "keep 5 m off sea floor" feature. I want to add an alternative dive schedule, where the boat dives to 50m while it's active, instead of just
