So a few thoughts specifically is allowing more tools to coordinate.
IE instead of saying in the clock "24 hours from now" it would be better to both include "24 hours from now" and also "at day5 13:00" that way when people get a delayed message they can still easily calculate timing for coordinated attacks.
Secondly.
More options for notifications. setting priority commands sound settings. Other such options.
Thirdly,
Would it be possible to set up "pathways" between nodes? More or less a road system that would allow faster transport. Flavor text could be ocean currents. Might be too complicated, but one issue I have seen is the affect of speed specialists. Allowing friendly nodes to say pay 25:50:100:150, drillers to "build a water way" might be valuable. This mechanic is mostly only for late game. Could also be a specialist mechanic as well.
Not sure how valuable these ideas are, they could be complete trash.
fourth is more of a question.
Are there plans to add more structure types, upgradable or specialist wise?
Thank you for this fantastic game! I have not EVER played a game as well crafted and designed as this before. (for IOS and Android).
