By default, all ufopaedia articles are assigned default visibility flag. The 'ufopediaRuleStatus' entry is only modifiable during gameplay via ufopaedia list (by right mouse button click on the entry).
Option to make specific article hidden by default will make possible to add proper ufopaedia entries for damaged/ruined facilities that will open, once you're clicking middle mouse button, but won't appear in the list nor will show up, when you switching to the next or previous ufopaedia entry.
So far I haven't found anything that allows me to make ufopaedia entry hidden on initialization or tech unlock.
Is there any chance to add something like this?
