Now if your top speed is something like 2000, wouldn't that make the "increase/decrease speed by 1/4" buttons kind of coarse? I wish we could change the amount that those buttons affect your speed... I hate controlling my ship's speed with the mouse, the slider's soooo tiny and speed is VERY vital to avoid crashing into things!
Of course in a Newtonian mod, most likely the pace of the game will be slower so you'll have more time to react, right?
And what's to stop the player from whizzing around the system at 8x timescale when he doesn't have any time-critical missions to complete? Instant acceleration!
