Hide Unavailable Items from Factoriopedia

[NLZ]

TL;DR

Hide items from Factoriopedia that are not yet available.

What?

Make it so Factoriopedia and other places only shows available items.
Inserter's filter is almost good, but even that has stuff slipped through (I see fluoroketone barrels withouth leaving the planet).
Optionally it could show unresearched stuff for planning.

https://mods.factorio.com/mod/hide-space-age-spoilers hides stuff from planets not yet available, although it's limited by manual revealing.
Alternative to Factoriopedia is https://mods.factorio.com/mod/RecipeBook which has this option to hide unresearched stuff.

Why?

As a first time player, seeing all the items in Factoriopedia is unnecessary and distracting.

As a setting I'd be ok with it, but I'm absolutely against this otherwise. I regularly look at the factoriopedia to check recipes and sometimes to get ghosts or set filters for things I don't yet have. It's very useful in planning. Hiding things may provide some level of excitement for some people on the first playthrough, but other than this single case it's pure downside.
