The "please wait" after opening a cargo box seems unnecessary. The contents are immediately applied, and any special contents are included in the log. What exactly are we waiting for?
Having nonillions of angel investors kinda renders this complaint silly, but the upgrade list eventually mixes cash upgrades with angel sacrifice upgrades. Perhaps splitting them in the list completely, or having a holy roller upgrades tab would be appreciated by more players than just me. FWIW I enjoy the micromanaging.
