Just a couple of quirks I've noticed regarding ship movement: firstly, if I click and move a ship while zoomed out, it's slow, and jerky and somewhat irritating. If I click the same ship, and zoom in as close as possible to the destination, and click the destination then BOOM, the ship gets there pretty much instantly. But zooming in and out to avoid slow ship movement is also somewhat irritating. If I click to the next 'Idle Ship" while first ship is moving, the game hangs while the first ship stutters towards its destination in pretty much the same way as it does if I don't click.

Second one, telling a single ship to join a fleet: occasionally the fleet AND the single ship move towards each other, and meet in the middle. The resulting fleet is displayed at a location that it is not at -  I can't select it or do anything with it, except by going to the ships list and finding/selecting that fleet, whereby it 'returns' to the original fleet location and can be clicked on / commands issued.

Everything else runs quick and smooth, no stability problems, everything seems to work well. Is there an option/setting to improve ship movement. I like Insane Maps, and late game with ships going 50-60 moves - and multiple fleets all over the place - these two 'quirks' put a damper on my full game immersion!
