I think it would be a great feature to be able to disable the auto-pause feature that pauses the game when you tab-out, open the chart, or any of the non-Options menu’s.
I get that with a game like this, the devs want to do everything they can to maintain immersion. But the fact is once you’ve discovered every single port in a region and are doing a little grinding for money or to unlock some story-lets via fetch quests, it would be 10-times less dreary if you could read through your journal, check your inventory, look over your character sheet, or even briefly tab-out to open a wiki, or message a friend, when partaking in an inevitably uneventful 160 second straight trip through empty space you’ve been through a hundred times before.
This game already did a FANTASTIC job at reducing the grind and commute time issues that were the only major bugbear in Sunless Sea, and allowing players to multitask a bit while commuting in the mid-late game would take it one more big step towards completely eliminate the problems entirely.
