Just a couple mods that I think should be added: Nice Text, Foxt's Minimal UI, and Glavius AI Tweak.

Some amazing quality mods that I can't play without are: Ruler Level System, Planet Raider,
Scientist Level Extension, Admiral Level Skills and Governor Level Extended.

I'm currently playing with ~ 114 active mods. While a huge number are simply sound and music mods, I like to share my collection:

Probably you could find additional inspiration for your 3-part-collection.

Can you add New Ship Class (NSC)?

StarNet AI

As the question asked before is it compatible with ship sets? And will it add NSC eventually?

Should be compatible with ship sets. I don't have permission to add nsc2 yet .

Got'cha! I hope you'll get it. This is a dream compilation for people who like a lot of mods and struggle with compatibility!

@Coulson

Instead of NSC, you may like to ask permission to include DNC mod:

The only ship mod that I consider to include is nsc2. If I get permission I will add it, if not no ship mod will be added

'War Name Variety' is a good one. Extragalactic Clusters also.

Sins of the Fallen Empires is a really nice mod that adds a new level of endgame tech and a
unique triggered crisis. (Along with all the accompanying mods that require it to run like ACOT)

The unofficial synthetic dawn DLC is a nice one that adds a lot of different mechanics to machine empires and makes them more vast in playstyles. I would consider this one essential.

The animated synthetic portraits also assists in creating a more diverse set of machines/synthetics and works well in tandem with the DLC.

I also second starnet AI, this really increases the intelligence of the AI. And in my opinion it is better than glavius' tweak.

sorry if this isn't the right section to say this but; short version: could you please upload the 3 parts of this somewhere in addition to here?

long version:
i have stellarius on the microsoft store (windows 10 junk app store), and the mods available from paradox's website... well... lets not talk about that, the point is, i found a way to download mods off the steam workshop and get them to play nice with my non-steam stellarius (lots of trial and error since its impossible to find any documentation to do anything for any game from the microsoft store), but i'm unable to download any of the 3 parts of this collection (2 when i originally tried) as they are far too large for any of the crappy websites i'v used to download workshop content, i love and use many of the mods here, and felt before painstakingly trying to get my current mods from breaking each other, it would be worth asking if you could publish/upload the mod elsewhere, such as paradox's website, mediafire, google drive even, idk, thanks if you even read this far let alone if you go through with my request

UI Overhaul Dynamic - Extended Topbar would be nice to have, I'd rather be able to track more things than see so much empty space on the top bar
