NOOOO I have to copy-paste here :))

Please add some sort of fix for terraforming, I went to just terraform my worlds to Gaia worlds, and it removed all the unique districts and plunged my empire into economic colapse, because 2 of my main energy generating worlds were using tidal power and wind power, which ment that those districts disapeared.

Please add maintenance drone jobs back onto hive segments on ring worlds.

Currently, if i start up a new game as a relatively normal non-ghestalt empire, i have many, many options when it comes to providing aminities on my planets. Holo-Theaters, Leisure districts on habitats, clerks, etc... It does not matter what origin i start with (any with an actual planet, void dweller, ring world) i have no issue keeping up with the aminities requirements of my pops.

Ghestalt empires are a different issue.

The way to generate aminities with a ghestalt empire is maintenance drone jobs, which you mostly get from the ghestalt's respective housing districts now that maintenance depots are no longer a thing. With District overhaul this still holds true for machine empire's nexus segments on ring worlds, however, hive segments do not generate maintenance drone jobs.

This cripples any ring world origin start with a hive mind and leaves you with very, very bad options for aminities on ringworlds. The only real way to generate aminities is to fill your building slots with hive warrens, but even this has a hard cap on how many buildings you can have per ringworld segment and you can have MANY more job segments and jobs left unused becouse you simply cant put any more pops on a ringworld before aminities become a major issue.

I do not know if there are options later down the line that unlock as you play but starting with the ring world origin as a hive mind with District Overhaul is almost unplayable. You would be better off abandoning your pops to nearby worlds and using it for energy credit generation seeing as hive districts on planets still give you maintenance drone jobs. However, it would simply be less of a headache to not start with the ring world to begin with if you did this.

Please add vanilla districts. Nerf them, but let us have them as an option in case of one bug or another

I think that the types of mining districts are too little.So I suggest adding mountain mining districts and vertical mining districts.
Also,I suggest making a decision called "Rules of Safe Operation",changing cheap-mines into normal mining districts but improving a little upkeep for miners(or reducing mineral output).Because I hate to disable any district from spawning(to make game more real),but planets with both cheap-mines and rare resources really make me in self-conflict.And I suggest Egalitarian states/societies will definitely use this decision on some of the planets with cheap-mines they colonized,especially the ones with Shared Burden civic will use this decision without considering the direct benefits or the reserve of resources(if it will require something more than influence to you).

How about a way to have multipel secondary districts? Because I feel it is kinda stupid that you can't have both a bueracratic and university district. At least for RP flavor, cause homeworld with nothing but cities and commercial districts is kinda dumb. Perhaps lock it behind an ascension perk, so it won't get to powerful
Also, is the dev still active?
