Creature reactions and tinted windows

Creatures should be able to see and somehow react to your presence if you’re looking or observing them through a window in your base. Like, building a base right near to the collector leviathan could offer some risk in that sense. At the same time, observing the creatures and leviathans from inside your base is pretty cool, so I think it would be nice if we could have some sort of tinted window option, where you (and thus the creatures) can’t see inside your base.

As for how reactions would go, that’s pretty dependant on the creature. Some could flee, others could maybe bash against the window (which could integrate into some sort of base/window integrity)
