Furthermore, it's explained nowhere that the Hush also increases travel time of probes, took me a while of double checking to verify it.
Lastly, it'd be very nice to have a "cancel expedition" button, maybe available only until 50% of the expedition - clicking it makes the probe return thus spending the same amount of time to come back, so if you cancel after 10s it'll take 10s to come back, cancel at 30 and it takes 30 to come back, and after 50% you can't cancel because there's less time left to come back than it has elapsed. Canceling research could also be interesting.
On a balance level, all civilization research appears basically useless to me, I have always been able to finish building the Ark waaaay before making my way through all green research. Tho not sure what a good solution can be.
