Minimized windows stay hidden when activating an app

Pieoneer is exclusively available on the Mac App Store. For most users, this isn’t just the most convenient option — it’s also the safest one, as every app offered there must first pass a review process. One of the technical requirements for being listed on the Store is that the app must be sandboxed, meaning it has to comply with tight security constraints. This is the reason why minimized windows of an app cannot be restored when activated through Pieoneer — the app simply has no access to them.
