Un-hide items

Make all items & fluids visible that are hidden by default, also those from mods. Can be useful for for filter and signal selection, which will be retained when this mod is uninstalled or when you create a blueprint. Note: To also view unresearched items in these selection lists, enable Settings → Interface → Interaction → Show all items in selection lists (this is part of vanilla Factorio).
Also has an option (in startup mod settings) to unhide recipes and to create dummy recipes for uncraftable items, and to add an overlay to hidden items.

This is a more elaborate version of https://mods.factorio.com/mod/unhide-items
