One more thing. Not really a bug, but more of an inconsistency.
While fitted to a ship, marking shield boosters disabled will remove them from shield metrics in the defense page while shield cell banks stay there for as long as they're fitted, even if they're disabled.
This is by design. If a shield booster is disabled then you lose its benefits, but due to the power usage of shield cell banks they are often configured so that only one or two are active at a time. As each set of SCBs are used up they are disabled and the next enabled, so their overall impact is displayed in Coriolis even if the power requirement means that they couldn't all be operational at the same time.
