I'd like to suggest some UI changes:

1. Disable con+firmation dialogs forever - There are a few con+firmation dialogs (e.g. cargo over quota, sea exploration) that can only be disabled for a day. It should be possible to disable these forever. Players who have been playing the game for more than a week surely never need to have these reminders again and all the con+firmation dialogs do is unnecessarily slow things down.

2. Clicking outside windows shouldn't close them - Sometimes, I spend time picking the right amount of goods to sell but accidentally miss the OK button and click outside the window, closing it and forcing me to do it again. It would be better if clicking outside did nothing and cancelling required explicit clicking of the cancel button.

3. Filter mates by current gear level - When equipping gear, I'd like the ability to apply this filter so that I don't have to click through each mate to see what they have.

4. Filter/sort cities that need investment - When looking at the list, I'd like to be able to filter cities that need investment so that I don't have to scroll the entire list.

5. Sort contracts in fortune shop from highest volume to lowest volume.

6. Deprioritise other messages during quest dialog - Sometimes, I'm in a quest dialog and a mate tells me that some goods are cheap in some far away city. I'd like that message from the mate to either appear behind the quest dialog or later on when the quest dialog has completed, as the quest dialog is more important.
