Aurora was deliberately switched away from that to enable drag-and-drop between multiple instances of the same window. To switch back would require nearly every window increasing in size to fit a multi-function drag-and-drop space.
That makes sense, however on a personal level it's extremely confusing so a toggle would be appreciated at least
Another suggestion I have that's probably a bit comprehensive.
With populations now being capped to planet size and growth being tied to the cap, it's now possible to have many small colonies that don't overcrowd and cause massive unrest problems. This means I now want to colonize a bunch of things and I think an overhaul to the mining system could really benefit here.
Nerf automines into the ground and make them only useful for deposits with easy availability. Make lower availabilities only mineable by regular mines staffed by actual people, and let those empty deposits continue to produce a trickle of resources once they run out. This will incentivize smaller, dedicated mining colonies and keep them relevant into the endgame as a source of essential materials. It will also be nice if this is coupled with deposits being vastly more common everywhere but the average deposit being very poor.
From a roleplay perspective I always want to colonize Luna and now that the population is capped very low this works perfectly for me for narrative purposes, Luna also having some tiny deposits that would produce at least a little bit of duranium for the duration of a whole game would be fantastic for story telling. Conversely, rare resources showing up in larger deposits on very high colony cost planets/moons would mean I have an incentive to terraform it to get to those, rather than fire and forget 200 auto mines and a mass driver.
