Which setting can disable Display (or maybe it's a HUD) things like...

Containers show empty or not but I'm wondering if there is a way I can either disable container popups entirely from BethINI.

NPC names from showing because I wouldn't know their name unless they told me.

I don't know about blocking the name, that's kinda of an internal mechanism, but there is: https://www.nexusmods.com/skyrimspecialedition/mods/1658

So, that one I tried before and it's neat but it shows a "?" to indicate unknown NPC and display their name after interacting with them/activating them.

I'm thinking more just to rely on my memory, so that I would never see their name unless I got to the point of an options or dialogue menu with them.

bShowSubtitleSpeakerName:Interface might toggle this if set to 0. As for containers, there probably is a mod.

I'll try that.

I also see bShowHUDMessages but I presume this is related to things like overencumbered warnings that appear on timers.
