Hi, been playing ST:NC for about a week now, and I'm enjoying it so far; however, I've got some ideas and suggestions here and there for what can be improved or added for more variety in future updates:

1) More Ascension Perk and Civic options for the Borg: they're rather lacking in those departments, and so they could use some additions to give them more flavor and mechanics to play with. One that note, more Ascension Perk options for everybody, really.

2) Speaking of, more "Planet-Killer" AP options like that the Romulans and Klingons and such get (such as the Thalaron Generator): there are a lot of wacky super-science gizmos in Star Trek that sadly aren't represented here, such as the Genesis Device, the Soliton Wave Generator, the Dreadnought Missile, etc. The UFP/Starfleet should get a few of these options, obviously, as they invented them in the first place (if for entirely different and benign purposes). The Borg in particular should get the Colony Ship from Armada II (replacing the current Pyramid design entirely), and it'd work just like base-game Stellaris's Nanobot Diffuser Colossus, assimilating entire planets with ease.

3) As for shipset additions: Starfleet is glutted with designs, so they don't need more right now, but for the other iconic majors, the designs from Birth of the Federation, Armada II, and the Fleet Ops mod could be included to give them some love and attention as well - the much of the A2:FO rosters for the Klingons, Romulans, Borg, and Dominion would be welcome additions (especially for the Dominion, as their shipset in ST:NC looks horrid, so they could do with a facelift), as would BotF's roster for the Ferengi and Cardassians, plus some of A2's roster for the latter (such as the Kulinor).

4) Lastly, some quality-of-life improvements: custom-themed UI's for the majors like ST:NH has, some streamlining of the shipsets, and bringing back the Sector management system from older Stellaris versions:
- for the first, just ask nicely for those UI's from the ST:NH team, they should be happy to share them?
- for the second, some shipsets (*cough*Starfleet*cough*) are enormously bloated, so could they be, like, consolidated into their general classes (Frigate, L. Cruiser, Cruiser, H. Cruiser, etc.)? I mean, instead of like, say, the Excelsior, Cardenas, and Akira being separate hulls, why not condense them under the "Battlecruiser" heading and make them ship-variants? For further consolidation, separate the period-specific designs into "2150/2200/2250/2300-era Battlecruiser" categories to keep the variant-selection window from getting clogged up.
- and for the third, the current "four-system-jump" automatic Sector creation system works as a baseline, but sometimes you just want to add/remove/rearrange a few specific systems so you can get nice, clean internal borders; the current system doesn't allow for that, but older versions of Stellaris had that functionality, so perhaps that could be brought back in somehow?

That should be everything I had in mind for now... oh, wait, one more thing:

5) Fix the issue regarding ships getting "Event Locked": it's really annoying to have one of my science ships get locked in-place somewhere due to some anomaly event and unable to do anything, or be able to get rid of it (the ship or the event that's locking it, I'm not picky). From what I can tell, it mostly occurs with the "Infected Forest" anomaly events (which appear to reference the TNG episode "Shades of Grey", which was one of the godawful Season 1 episodes).

There, now that should be everything!
