Your storage box, one key away

In SIGNALIS, deciding what to carry is part of the tension. Storage Box Anywhere lets players relax one part of that routine by opening the familiar storage interface with a shortcut, F2 by default, instead of returning to a storage box every time they need to swap supplies.
Tolspy98 keeps the shortcut inactive during cutscenes, dialogue, menus and loading. The mod specifically requires MelonLoader 0.5.7, not 0.6 or later. An optional setting can bypass normally restricted inventory areas, but the creator hasn't tested it against every scripted sequence.
