Few things to make the game better.
Please remove the stupid feature of being able to only add 4 ships to museum when you level it up (or at leas make it so that you can level it up endlessly). I am at level 407, museum at level 32, full, and I have 482 ships in total. My fleet size is 46 anchors, so as you can see, majority of my ships are just "there" taking up inventory space, and makes scrolling to the very last ship tedious swiping left hell.
2) Ship sorting under "your ships"
It is always sorted in a way that makes sense when hauling cargo. So the best cargo ship is first (cargo per anchor) and worst cargo ship is last (where you have to swipe 20 times to get, as mentioned in previous suggestion). Please add button "swap sort" button to swap the current sort order to "sort by sailor size" and back.
When I have sailor missions to complete, it is always hassle to find my best sailor ships in middle of the 400+ ship "parking lot". I have 1000, 800 and 500 sailor ships that are in the middle of the list with 100, 60 and 50 cargo slots.
