After designating fleets using numbers one to nine on the keyboard, once I tap the number of the fleet, I am shown the cluster of stars where the fleet is located, and it is up to me to zoom in with the middle mouse roller and look for the specific planet  where a fleet is located.

Suggestion:  I think it would be better that after tapping once or twice on the designated number on the keyboard, we would immediately be brought to the planet where the fleet with the pre-designated number is located so that we won't waste precious moments in having our fleet being decimated by mines or the opponents' ships.
