Space Stations--Pros/Cons

[General Hawkwing]

A lot of thoughts on the cons of space stations, any thoughts on the pros I listed.
One "realism idea" I wrestled with was the ability of stations to be merged with a fleet, transfer supplies to the fleet and then when the ships left still have full supplies. My work around thought is that the station receives numerous visits from trader vessels, which carry on the daily trading activity that is beneath the notice of us empire builders.
