Skyrim SE and VR use the same section of the website and always have, so the downloads appear for both games. 

If you click the "Group" button on the category header you can achieve pretty much exactly what you're asking. 

 
If you don't like the site-given category you can also create your own. 

This is a bug introduced by a website update this morning. We're fixing it now. Sorry about that! 

This issue was resolved years ago. If you are still seeing it update Vortex to the latest version and ensure that you uninstall any old BG3 support extensions from the extensions section. 1.5.3 is the latest version. 

NMM hasn't been supported since 2016. If you need help with it you'll need to contact the current maintainers. 
Vortex has an option in the downloads section of Settings to control if it handles downloads from the site or not. 

After looking at the results of the test I did yesterday, we've decided the best course of action right now is to increase the daily API quota from 10,000 to 20,000. This should allow 2-3 large collections to be downloaded per day. 
While it is still possible to hit the limit, it should be harder to do so. 

This is a detection issue, it looks like your EXE file is different. 
You can report it to the extension creator here: https://www.nexusmods.com/site/mods/1058

Please see this thread for info on this issue: 
 

The automation settings do not apply to collections, they never have. 
Those errors are usually suppressed though, restarting the app might help. Some of them will show regardless though - the downloads not finalised ones are important so they appear when you download a corrupted file. 

You can install game extensions directly from their associated download page if your setup is so messed up you can't find it in the app.

We won't be building this into Vortex, but it may be possible to add it to our new app when that is fully developed. 

You should never remove these files manually, it should be done in the Vortex UI.
If you want to do this in batch Ctrl + A, Ctrl + Click and Shift + Click all work in the mods table. 

Please manually install the latest version of Vortex over your current install to fix this. 
You have a super old version that cannot auto-update. 

You have a very, very old version of Vortex installed. Please update to the latest version and try again. 

Go to the Games tab, find Subnautica, click the little menu on the card and select "Manually Set Location". Pick the folder for your Steam install and restart Vortex once it has been accepted. 
 

This is a fault with the Warhammer 40k Darktide extension (as noted in the second line of the error). 
You can report it here: https://www.nexusmods.com/site/mods/684
Alternatively, you should uninstall it from the Extensions section. 

If you're getting an error in-game that isn't a problem with Vortex it'll be some kind of issue with QMM. You may want to check the mod pages you're using for advice. 

This was most likely a temporary issue related to a site issue on the day you posted this. 

It's not something you can do in the UI, but Vortex is open source so you can contribute the required changes if you're a developer.

Any archived file can be downloaded if you know the IDs for it. You can aks the mod author on their page to un-archive it if you don't have this information though! 

This doesn't appear to be related to Vortex, please see this article for further help: https://help.nexusmods.com/article/92-im-having-download-issues-what-can-i-do

If it's not there, it's not installed. So download the file manually from the mod page and drop it into the "Drop Files" section on that page. 

If your Vortex setup is entirely broken, you should delete the Vortex folder under %Appdata%\Vortex to reset everything. 
This will "forget" all games/mods/settings you have and you may need to manually clean up your game folders. 

Go to Settings -> Mods and move the staging folder to the same drive as the game.
You also need to ensure you're doing this on an NTFS hard drive (not an external drive).
