Possibly some feature request, but some are just wrong.

Bridges should not be affected by internal or external tanks, just basic hull size.

Exterior demountable tanks are handled incorrectly: they are external, so should not consume space inside the hull, but should explicitly by RAW affect drive performance (just like retained drop tanks).

By RAW ships must have a full load of fuel (which may be in external tanks). The fuel purifier must be dimensioned for all fuel tankage, so at least a full load. It's not now. I call that incorrect behaviour.

RAW is pretty clear, as far as I can see:

I agree that if you add more fuel tankage in drop tanks or demountable tanks after the ship is designed, the fuel purifier need not be changed. Any external tanks always changes drive performance.

Letting the user do what he wants is great, but the app should default to RAW IMHO.

A feature request would be for an optional validation system that checks that the ship is correct by RAW, even if the user adjusts to taste. That way a player can hand his design to the Referee with a clear "Validated" mark.

Possibly, I haven't tested all possibilities, but a few cases from 200 Dt to 1800 Dt. With no internal jump fuel, any drop tank at all combined with a standard LBB2 jump drive leads to error.

Add J-1 internal jump fuel or a custom jump drive and the error disappears.

The computer draws power. Hence a ship with a PP-4 and that computer cannot have enough free power for Agility 4. See the example:

The app calculates power production and hence agility incorrectly in this case. Makes sense?
