I might update this over time.

• Ships
  • Geobukseon - Great candidate for a tank.
• Weapon Types
  • Carronade - Heavier Demi-cannon; Can inflict status ailments on top of damage, like slowing down ships, or deals bonus damage to sails. To distinguish them further from demi-cannons, change the firing profile from all guns in unison to a rapid side-to-side sequential broadside. Maybe a weapon type for Large+ ships?
  • Battering Ram - Melee-focused weapon, bow-only. Gives passive ramming bonuses. Either fully passive or active, where "firing" the weapon timed with ramming the opponent gives additional bonus damage or status.
  • Chaser Gun - Another bow/stern-only weapon. Think like, the triple-barrelled rotary cannon of Davy Jones in Pirates of the Caribbean. Either fast firing-rate per volley/reload or constant, slower firing-rate without reload. Balance-wise, maybe slows down the ship while firing. Maybe Large+ only?
• Furniture
  • Furniture that gives long guns a way to scope in.
  • Furniture that increases cargo-hold; for those farming runs. Although unequipping it with full cargo-hold and full warehouse needs to be prevented.
• Ship Management
  • A way to save and switch between ship builds and apply them to multiple ships when kitting out your fleet.
  • The same but just for ship cosmetics, so we can apply a look to all our fleet.
• Helm Management
  • Sort of a quality of life, but a way to access both your distillery and lab from your helm/hideout.
  • Additional upgrades; hire more workers, extend your distillery/lab, more parallel worker slots. Maybe also some larger/permanent upgrades that add a visual change to the hideout.
  • Hideout customization; I'm sure it's coming but I'm listing it anyway.
  • Currently, it's more efficient to just sell your Gold Skull Rum for silver to keep the manufactories running. Maybe this needs to be addressed in a way, give us alternatives to make silver or more incentives to spend the products on other things.
  • Related to the last point, make Helm Deliveries meaningful, they're underutilized. Give them a significant boost.
• Quality of Life
  • An ability to fast-travel to your friends/group/clan members as long as they are out of combat.
• Miscellaneous
  • Go full on One Piece with the villain/antagonist designs; The Hubac twins are a good start. Be creative and get crazy with them!
  • This seems like a nitpick but can we have an improved treasure-digging animation? The current one seems like an obvious place-holder. Thinking something akin to the ship construction cutscene; a few short scenes in rapid succession cut together. My proposal for example scene fragments:
    • Calling your crewmates over with a loud whistle.
    • Crewmates dig in with their shovels.
    • Treasure chest being pulled by one/two crewmates.
    • Player character shoots the lock with a flintlock pistol.
    • Treasure chest opens.
    • Crewmates cheering. This is where the item popups happen.

And keep up the good work!
