Salve, rmmCC!
Hoping that I have correctly understood your questions, I answer:
Q1. Click on "Mark Site Read."
Q2. An orange colored round icon next to a topic.
Q3. Not sure.  Maybe a star next to a topic?  Anyway, I am still working on this.

In Vortex: plugins page, upper right-hand corner.

You may want to raise this issue in the Syrim SE support forum: https://forums.nexusmods.com/forum/8877-skyrim-se/.  This is the Vortex support forum.

The absence of a plugins page in Vortex is intentional. See here under "What's Next?": https://www.nexusmods.com/news/14883,

Vortex did nothing wrong. By default Vortex places game downloads and staged mods in AppData\Roaming\Vortex. However, you can override those defaults in Vortex settings and place the directories elsewhere. Remember, though, that hard link deployment requires that the game and the mod staging folder be on the same drive.

Look for YouTube videos about tomb raider mod installation. I bet there's a ton of them.
 
Also, look for a mod manager that supports your game. There's probably a few of those around.
 
Since this is not a Vortex issue, this is the best advice that I can give you.

In the modded profile, what would happen if you simply disabled the plugin for Immersive Music but not the mod itself? Would that not "hide" the esp file but retain the loose files? Or have I totally misunderstood what you are trying to do?

Have you tried raising these issues in a Fallout NV support forum? These problems do not seem to be Vortex related.

LOOT is integrated into Vortex. You do not need to run LOOT separately. Just let Vortex do the sorting. Vortex will also display LOOT messages on the plugins page.

This warning occurs when Vortex detects incorrect BSA versioning for mods used in Fallout 3, Fallout NV, the two Skyrims, and/or Fallout 4. It is not an error. Rather the warning arises from the fact that some mod authors, in creating mods for the aforementioned games, possibly used the wrong tools when packaging their BSAs. Vortex is simply reporting this discrepancy and suggesting a course of action should there be problems such as the game crashing on load.
 
The following article explains: https://wiki.nexusmods.com/index.php/Bethesda_mod_archives
 
I myself have experienced this "incompatibility" most often with some Fallout 4 mods, but less so with Fallout NV and Skyrim mods. In all cases, the so-called "Oblivion" BSAs were not incompatible at all. After a couple of warnings, Vortex ceased the alert.

Yes, or use a game specific mod manager. Currently Vortex supports approximately 250 games, including RE2. I'm not aware of any Batman support.

On the mods page double-click on a mod and open up its info panel. There you'll find a place for notes.

You would be better served by posting this in a Fallout 4 support forum. This is not a Vortex issue.

There's no 32-bit version of Vortex. The developers have stated they have no plans to offer one.

Nexus Mods is a website that hosts mods for various games (2,014 to date). Vortex is a mod manager that can manage those games' mods, provided that it has been programmed to do so. Thus far game extensions have been written for ~240 games out of the 2,014 games whose mods are hosted on Nexus Mods. If you are so inclined, you can write and submit an extension for your favorite game using the following template: https://nexus-mods.github.io/vortex-api/2022/04/03/Creating-a-game-extension.html.
 
For the games currently managed by Vortex, open Vortex and click on "Games."

On the Vortex dashboard the currently managed game shows up in the uppermost left hand corner. Do you see Fallout 4 there?

This mod has some issues quite apart from Vortex, as can be seen from user posts and bug reports. You probably should try for help in a Skyrim SE support forum rather than here.

There is a pinned thread on this topic in Vortex Support: https://forums.nexusmods.com/index.php?/topic/7024131-vortex-for-linux/.

Have you read the pinned post "Microsoft .NET" at the top of the Vortex Support page?

This is not a Vortex issue. Please post in the appropriate game support forum.

Download the Vortex custom installer.

Have you checked the upper left hand corner of your dashboard?

A couple of years ago I had a similar problem, which Pickysaurus resolved for me. See this forum thread: https://forums.nexusmods.com/index.php?/topic/8813288-vortex-1216-and-the-witcher-3/page-2?hl=witcher&do=findComment&comment=82109253.
 
I hope this helps.
