The sector space revamp on Tribble is... WOW! Just Wow! This is how I imagined STO would be! The nacelle grills are brighter when in sector space, they don't glow more when going faster, like they did in an experimental stage, which looked ugly. (But IMO they should only glow more while accelerating) And the toggle-able 'astrometrics' is brilliant.
Also included is a Z-axis update, you can now climb at 60 degrees rather than 45. Now they just need to sort out the Intrepid (& variants) nacelle positions and the Quantum slipstream effect.
Bugs on the server include the dreaded 'ship falling through space' (only for a split second though). and the camera returning to the previous view after warp/beam out.
